Clear Temporary Files and Cache
1.1 Clearing Temporary Files
When you are facing the “WordPress Error Failed to Write File to Disk,” one possible solution is to clear your temporary files. Temporary files are generated by your operating system and applications, including WordPress, and can take up valuable disk space. Over time, these files can accumulate and cause issues with writing files to the disk.
To clear temporary files, you can use the built-in disk cleanup utility on your computer. For Windows users, you can access this utility by searching for “Disk Cleanup” in the Start menu. For Mac users, you can open the “Finder” application, click on the “Go” menu, and then select “Go to Folder.” In the text box, type “/private/var/folders” and press enter. This will navigate you to the temporary files folder, where you can manually delete the files.
1.2 Clearing Cache
Clearing your cache is another step you can take to resolve the “WordPress Error Failed to Write File to Disk” issue. Cached files are copies of website elements that are stored on your computer or web server to improve loading times. However, these files can become corrupted or outdated, causing conflicts with the disk-write process.
To clear your cache, you can use a WordPress caching plugin or utilize your web browser’s built-in functionality. If you are using a caching plugin, navigate to the plugin’s settings and look for an option to clear the cache. Follow the provided instructions to complete the process. Alternatively, if you want to clear your browser cache, go to your browser’s settings or preferences and locate the cache clearing options. Remember to select all relevant options to ensure a complete cache clearance.
Change File Permissions

2.1 Checking File Permissions
File permissions dictate the level of access that various users or processes have to files and directories on your server. Incorrect file permissions can cause the “WordPress Error Failed to Write File to Disk” as they might prevent WordPress from saving changes or uploading files to the disk.
To check file permissions, you can use an FTP client to connect to your server. Once connected, navigate to the directory where the file in question is located. Right-click on the file and select “File Permissions” or “Properties.” This will display a numerical value or a set of checkboxes representing the file permissions.
Ideally, directories should have a permission value of 755, while files should have a permission value of 644. If the permissions are different, you can change them accordingly.
2.2 Changing File Permissions
In case the file permissions are incorrect, you can modify them to resolve the “WordPress Error Failed to Write File to Disk” issue. There are multiple ways you can change file permissions, but using an FTP client is the recommended method.
To change file permissions via FTP, navigate to the desired directory and right-click on the file or folder in question. From the context menu, select “File Permissions” or “Properties.” This will open a dialog box where you can modify the permission values.
Enter the correct numerical value for directories (755) or files (644) in the appropriate field or select the checkboxes to match the desired permissions. Once you have set the correct permissions, click on the “OK” or “Apply” button to save the changes.
Increase PHP Memory Limit

3.1 Editing php.ini File
The PHP memory limit determines the amount of memory that your WordPress website can consume while executing scripts. If your website exceeds the allocated memory limit, it can result in the “WordPress Error Failed to Write File to Disk.” To address this issue, you may need to increase the PHP memory limit.
To edit the php.ini file, you will need access to the server’s file system. Use an FTP client to connect to your server and navigate to the root directory of your WordPress installation. Look for the php.ini file and download it to your local machine.
Once you have downloaded the php.ini file, open it using a text editor. Look for the line that defines the PHP memory limit. This line typically looks like “memory_limit = 128M.” Increase the value to a higher value, such as “256M” or “512M,” depending on your website’s requirements. Save the changes to the php.ini file and upload it back to the server, overwriting the existing file.
3.2 Editing .htaccess File
If you do not have access to the php.ini file or your server does not use it, you can also increase the PHP memory limit through the .htaccess file. The .htaccess file is a configuration file that allows you to make changes to how your web server behaves.
To edit the .htaccess file, connect to your server using an FTP client and navigate to the root directory of your WordPress installation. Look for the .htaccess file and download it to your local machine.
Once you have downloaded the .htaccess file, open it using a text editor. Add the following line of code at the end of the file: “php_value memory_limit 256M” (replace “256M” with the desired memory limit). Save the changes to the .htaccess file and upload it back to the server, overwriting the existing file.

4.1 Deactivating Plugins
Conflicts between WordPress plugins can sometimes lead to the “WordPress Error Failed to Write File to Disk.” By deactivating all plugins, you can determine if any of them are causing the issue.
To deactivate plugins, access your WordPress dashboard and navigate to the “Plugins” section. Select all the plugins by clicking on the checkboxes next to their names or select the “Bulk Actions” dropdown menu and choose “Deactivate.” Click on the “Apply” button to deactivate the selected plugins.
Now, try performing the action that was previously causing the error. If the error no longer occurs, it is likely that one of the plugins was responsible. To identify the problematic plugin, reactivate the plugins one by one and test the action after each reactivation. Once the error reoccurs, you will have identified the plugin causing the issue.
4.2 Renaming Plugins Folder
In some cases, you may not be able to access your WordPress dashboard to deactivate the plugins. In such situations, you can disable the plugins by renaming the plugins folder via FTP.
Connect to your server using an FTP client and navigate to the root directory of your WordPress installation. Locate the “wp-content” folder and inside it, find the “plugins” folder. Right-click on the “plugins” folder and choose the “Rename” option. You can give it any name of your choice, such as “plugins_old.”
Now, try accessing your WordPress dashboard. Since the plugins folder has been renamed, WordPress will not be able to find and load any plugins. If the error no longer occurs, it confirms that one of the plugins was causing the issue. To identify the problematic plugin, revert the name of the folder back to “plugins” and rename each individual plugin folder within it one by one. After renaming each plugin folder, test the action that was previously causing the error until you identify the specific plugin causing the problem.

Upgrading your WordPress installation to the latest version not only ensures that you have access to the latest features but also helps address any known issues or vulnerabilities. To upgrade WordPress, follow the steps outlined below.
Step 1: Back up Your Website – Before performing any major updates, it is crucial to create a backup of your WordPress website. This will allow you to restore your website in case anything goes wrong during the upgrade process.
Step 2: Check Compatibility – Ensure that your theme and plugins are compatible with the latest version of WordPress. These compatibility requirements are usually mentioned on the respective theme or plugin’s documentation or website. If any of your currently active themes or plugins are not compatible, consider updating them to the latest versions or finding alternative solutions.
Step 3: Update WordPress – To upgrade WordPress, access your WordPress dashboard and navigate to the “Updates” section, as explained earlier. Click on the “Update WordPress” button to start the upgrade process. WordPress will automatically download and install the latest version.

Check Server Space

6.1 Assessing Disk Space
Insufficient disk space can cause various errors, including the “WordPress Error Failed to Write File to Disk.” It is crucial to regularly assess the available disk space on your server to prevent such issues.
To check your server’s disk space, you will need access to your hosting account. Most hosting providers offer a control panel or dashboard where you can find information about your disk space usage. Look for options like “File Manager,” “Disk Usage,” or “Storage” to view the details.
Once you have accessed the disk space information, check if you are approaching or have exceeded the allocated disk space limit. If you are nearing the limit, consider freeing up some space by removing unnecessary files or upgrading to a higher hosting plan with more disk space.
6.2 Cleaning Up Unnecessary Files
If you have identified that your server is running low on disk space, it may be necessary to clean up unnecessary files to resolve the “WordPress Error Failed to Write File to Disk.” Here are some steps you can take to free up space.
Delete Unnecessary Plugins and Themes: Access your WordPress dashboard and navigate to the “Plugins” or “Themes” section. Deactivate and delete any plugins or themes that you are no longer using.
Remove Media Files: If your media library contains large files or duplicates, consider deleting them. You can access your media library through the “Media” section of your WordPress dashboard. Be cautious when deleting files, as this action cannot be undone.
Empty Trash: When you delete posts, pages, or comments, they are moved to the trash. Emptying the trash permanently deletes these items, freeing up disk space. To empty the trash, go to the respective sections (Posts, Pages, or Comments) in your WordPress dashboard and look for the “Trash” or “Bin” option. Select all the items and choose the “Empty Trash” option.
By following these steps, you can create more available disk space on your server and potentially resolve the file writing issue.
Verify File Ownership
7.1 Checking File Ownership
Incorrect file ownership can prevent WordPress from writing files to the disk and result in the “WordPress Error Failed to Write File to Disk.” To check file ownership, you will need access to the server’s file system.
Using an FTP client, navigate to the root directory of your WordPress installation. Right-click on a file or folder and select “File Permissions” or “Properties.” Look for the owner or group information, usually displayed as a username or numeric value.
Ideally, all files and folders within your WordPress installation should be owned by the same user or group that the web server runs as. The most common ownership values are “www-data” or the username associated with your hosting account. If the ownership is different, it may need to be changed.
7.2 Changing File Ownership
To address file ownership issues, you will need access to your server’s shell or SSH access. Contact your hosting provider for guidance on changing file ownership, as the process can vary depending on the server configuration.
In most cases, the “chown” command is used to change file ownership. The command typically follows the format:
chown [owner]:[group] [file]. Replace
[owner] with the desired owner,
[group] with the desired group, and
[file] with the file or directory you want to modify.
By setting the correct file ownership values, you can ensure that WordPress has the necessary permissions to write files to the disk and resolve the error.
Use FTP Instead of Direct File Upload
8.1 Installing and Configuring FTP Client
Using FTP (File Transfer Protocol) instead of direct file upload can help overcome any limitations or restrictions imposed by your hosting environment. By setting up and configuring an FTP client, you can securely transfer files between your local computer and the server.
To install an FTP client, search for popular options like FileZilla, Cyberduck, or WinSCP. Once you have downloaded and installed the FTP client of your choice, open it and navigate to the “Settings” or “Preferences” section.
In the settings, you will need to provide the FTP connection details, including the server address, port number, username, and password. Contact your hosting provider if you are unsure about these details. Once you have entered the necessary information, save the settings.
8.2 Transferring Files via FTP
After configuring the FTP client, you can start transferring files between your local computer and the server. To upload files to the server, open the FTP client and connect to your server using the provided connection settings.
Once connected, navigate to the appropriate directory on the server where you want to upload the files. On the local computer, locate the files you want to upload and select them. Drag and drop the selected files from your local computer to the server directory in the FTP client’s interface.
If you encounter any file writing errors during the direct file upload process, using FTP can serve as an effective alternative.
