Verify PHP Installation
Check PHP Version
To verify your PHP installation, start by checking the version of PHP that is currently installed on your server. This information is crucial as it determines the compatibility of your server with WordPress and its various plugins and themes. To check the PHP version, you can create a simple PHP file and run it on your server.
Create a new file called phpinfo.php in your website’s root directory and add the following code:
</?php>Save the file and open it in your web browser by navigating to http://your-domain.com/phpinfo.php. You will see a comprehensive page containing information about your PHP installation, including the PHP version.
Ensure PHP is Installed
If you have confirmed that PHP is not installed on your server or you encounter any issues accessing the phpinfo.php file, you will need to install PHP. The installation process may vary depending on your hosting environment. It is recommended to reach out to your hosting provider for guidance on how to install PHP if it is not already available.
Restart PHP Service
If you have made any changes to your PHP configuration or installed PHP for the first time, it may be necessary to restart the PHP service on your server to apply the changes. Restarting the PHP service ensures that the modifications take effect and your server can recognize PHP. You can usually restart the PHP service through your hosting control panel or by contacting your hosting provider for assistance.
Check PHP Configuration
Checking your PHP configuration is crucial to ensure that all the necessary settings are in place for WordPress to function correctly. By reviewing the PHP configuration, you can identify any discrepancies or missing components that may be causing the “PHP is not running” error.
To access the PHP configuration file (php.ini), you will need to locate it on your server. The location of the php.ini file may vary depending on your hosting environment. Once you have located the file, open it using a text editor and review the settings. Pay attention to directives such as memory_limit, post_max_size, and upload_max_filesize, as these can affect the performance and functionality of your WordPress site. Make sure they are set to appropriate values according to your requirements.

Check WordPress Installation
Verify WordPress Files
When encountering a “PHP is not running” error, it is essential to verify the integrity of your WordPress installation. Ensure that all the necessary files are present and have not been corrupted or modified unintentionally.
To verify your WordPress files, you can compare your installation with a fresh WordPress installation. Download the latest WordPress version from the official website and compare the files in your installation with the fresh files. Look for any missing or modified files that may be causing the error. Replace any missing or modified files with the correct versions to restore the integrity of your WordPress installation.
Check File Permissions
Incorrect file permissions can prevent PHP from running properly and lead to the “PHP is not running” error. It is important to ensure that the correct file permissions are set for your WordPress files and directories.
Typically, directories should have a permission setting of 755, while files should have a permission setting of 644. You can modify file permissions using an FTP client or through your hosting control panel’s file manager. Review the permissions of your WordPress files and make any necessary adjustments to ensure they are set correctly.
Update WordPress Core
An outdated version of WordPress can contribute to the “PHP is not running” error. WordPress releases regular updates that include security patches, bug fixes, and other enhancements. By keeping your WordPress core up to date, you can ensure optimal performance and minimize the occurrence of errors.
To update your WordPress core, navigate to the “Updates” section in your WordPress dashboard. If an update is available, click the “Update Now” button to initiate the update process. It is important to create a backup of your WordPress site before performing any updates to avoid any potential data loss or disruptions.
Disable/Remove Faulty Plugins and Themes
In some cases, a faulty plugin or theme can conflict with PHP, resulting in the “PHP is not running” error. It is important to identify and disable or remove any plugins or themes that may be causing the issue.
Start by deactivating all plugins on your WordPress site. This can be done by navigating to the “Plugins” section in your WordPress dashboard and selecting the “Deactivate” option for each plugin. After deactivating all plugins, check if the “PHP is not running” error still persists. If the error is resolved, you can gradually reactivate each plugin one by one to identify the specific plugin causing the issue.
