 If you've encountered issues during your WordPress site's automatic
 upgrade, specifically with the `wp-includes/option.php` file, take these
 steps to resolve the problem. Begin by backing up your entire site,
 including files and the database. Download the latest WordPress version,
 extract the files, and replace the corrupted `option.php` file on your
 server with the new one. Check for issues in other critical files within
 the `wp-includes` folder, ensure correct file permissions, and confirm PHP
 version compatibility. Clear your browser cache, then thoroughly test your
 site for functionality. Investigate any failed file copy during the
 automatic upgrade by examining server logs. Seek assistance on the
 WordPress support forums or consult professionals if issues persist.
