 To resolve the issues you're experiencing on your WordPress site, follow
 these steps systematically:

 1. Check Browser Console for Errors:
 Open your WordPress admin dashboard.
 Press F12 to open the Developer Tools.
 Go to the "Console" tab and perform the actions that are not working
 (e.g., Quick Edit, Set New Password).
 Note any error messages that appear in the console. These can provide
 clues about what might be going wrong.
 2. Clear Browser Cache and Cookies:
 Sometimes, cached files can cause issues. Clear your browser's cache and
 cookies and try again.
 3. Ensure All Plugins and Themes Are Updated:
 Make sure all plugins and themes are up-to-date. Outdated software can
 cause compatibility issues.
 4. Disable All Plugins:
 Deactivate all plugins and check if the issue persists.
 If the problem is resolved, reactivate the plugins one by one to identify
 the problematic plugin.
 5. Switch to a Default Theme:
 Temporarily switch to a default WordPress theme (e.g., Twenty Twenty-One)
 to see if the issue is theme-related.
 6. Check for JavaScript Conflicts:
 JavaScript errors can cause the admin area to malfunction. Check for
 conflicts by:
 Disabling all plugins and using a default theme.
 Enabling the SCRIPT_DEBUG mode by adding the following line to your wp-
 config.php file:

 define('SCRIPT_DEBUG', true);

 This will load the unminified versions of the scripts and can help
 identify the source of the issue.
 7. Check File Permissions:
 Ensure that your WordPress files and directories have the correct
 permissions:
 Files: 644
 Directories: 755
 8. Increase PHP Memory Limit:
 Sometimes, insufficient PHP memory can cause issues. Increase the PHP
 memory limit by adding or modifying the following line in your wp-
 config.php file:

 define('WP_MEMORY_LIMIT', '256M');

 9. Check for Corrupted Core Files:
 Download a fresh copy of WordPress from wordpress.org.
 Replace the wp-admin and wp-includes directories on your live site with
 the ones from the fresh download (except for wp-config.php and the wp-
 content directory).
 10. Consult Hosting Provider:
 Contact your hosting provider to check for any server-side issues that
 might be causing the problem.
 11. Compare Live and Staging Site Configurations:
 Since the staging site works fine, compare the configurations and server
 settings of both the live and staging sites. Look for discrepancies in
 server settings, PHP versions, or any other configurations.
 12. Enable WordPress Debug Mode:
 Enable debugging in WordPress by adding the following lines to your wp-
 config.php file:

 define('WP_DEBUG', true);
 define('WP_DEBUG_LOG', true);
 define('WP_DEBUG_DISPLAY', false);

 This will create a debug log in the wp-content directory named debug.log.
 Check this log for errors that might indicate the source of the issue.
 If after following these steps the issue is still not resolved, you can
 provide the error messages from the browser console or the debug.log file
 for further assistance.

 By methodically working through these steps, you should be able to
 identify and resolve the issues affecting your WordPress site.
