If autosave and revisions are not working in WordPress, there are a few steps you can take to troubleshoot and potentially resolve the issue:

1. Check Autosave Interval:

   • WordPress has a default autosave interval of 60 seconds. If you want to adjust this, you can use the following code in your wp-config.php file:
   php

• define('AUTOSAVE_INTERVAL', 120); // Set to 120 seconds (2 minutes)

  Be cautious about setting this too low, as it may increase server load.

• Check Browser and Network Connection:

  • Sometimes, issues can be browser-specific. Try using a different browser to see if the problem persists. Additionally, ensure you have a stable internet connection.

• Check for JavaScript Errors:

  • Open your browser's developer tools (usually by pressing F12 or right-clicking and selecting "Inspect"). Go to the "Console" tab and look for any JavaScript errors. These could be causing the autosave and revisions features to fail.

• Check for Plugin Conflicts:

  • Deactivate all plugins and see if the autosave and revisions work. If they do, reactivate the plugins one by one to identify the conflicting plugin.

• Check for Theme Conflicts:

  • Switch to a default WordPress theme (like Twenty Twenty-One) temporarily and see if autosave and revisions start working. If they do, there may be an issue with your current theme.

• Increase PHP Memory Limit:

  • If your server has a low PHP memory limit, it may be preventing autosave and revisions from working properly. You can try increasing the memory limit in your wp-config.php file:
  php
• define('WP_MEMORY_LIMIT', '256M');

• Check File Permissions:

  • Ensure that the wp-content directory and its subdirectories have the correct permissions. They should typically be set to 755 or 775 (depending on your server configuration).

• Check Database Health:

  • Sometimes, database corruption can lead to issues with autosave and revisions. You can use a plugin like WP-Optimize to clean and optimize your database.

• Disable Security Plugins:

  • Some security plugins may have settings that interfere with autosave and revisions. Temporarily disable any security plugins you have and test if the features work.

• Enable Debugging:

  • Enable WordPress debugging by adding the following line to your wp-config.php file:
    php

10. • define('WP_DEBUG', true);
      This may provide additional information about what's causing the issue.

11. Contact Hosting Provider:

    • If none of the above steps work, contact your hosting provider for assistance. There could be server-related restrictions.

Always remember to back up your website before making any significant changes. If you're not comfortable with these steps, consider seeking help from a web developer or your hosting provider's support team.
