 * The Rank Math plugin is amazing and I use it in all my projects, but in this 
   particular one it performs a very abrupt level of requests, reaching 100% of 
   CPU usage and 100% of the server’s physical memory usage. The online store is
   very slow and we can’t use Rank Math because it blocks the server, if we deactivate
   it everything goes correctly. What can we do? I need to use this plugin, but 
   not in these conditions.
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fserver-cpu-usage%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * I have the same issue here on [http://www.antepbaklava.bg](http://www.antepbaklava.bg).
   I receive emails that say: “Your Site is Experiencing a Technical Issue”
 *     ```
        In this case, WordPress caught an error with one of your plugins, Rank Math SEO.
   
       To keep your site safe, this link will expire in 1 day. Don't worry about that, though: a new link will be emailed to you if the error occurs again after it expires.
   
       When seeking help with this issue, you may be asked for some of the following information:
       WordPress version 5.7
       Current theme: Bakery (version 2.6)
       Current plugin: Rank Math SEO (version 1.0.61)
