 * Hello! all sites stopped working for me, instead of the site the inscription “
   The site has encountered a critical error. Please check the administrator’s inbox
   for further instructions.
 * Learn more about troubleshooting WordPress.”
 * I can’t log into the admin panel either, there is also an inscription about the
   problem. A letter comes to the mail where it says that the Redis Object Cache(
   version 2.1.4) is to blame for the problem
 * WordPress version 6.0.1
    Current Topic: Cook It (version 2.1.6) Problem plugin:
   Redis Object Cache (version 2.1.4) PHP Version 8.1.6

 * Version 2.1.4 had some SVN issues. Try installing 2.1.6 ✌️
 * If you can’t access the admin, make sure to delete the `wp-content/object-cache.
   php` file.
