Slow Editor and errors

Hello,

We apologize for the issue you are facing with the slow Editor and the errors when trying to save posts or pages. Thank you for providing the error details, as it helps in diagnosing the problem.

The error you encountered, Failed to execute 'removeChild' on 'Node': The node to be removed is not a child of this node, suggests that there may be a JavaScript conflict, possibly caused by another plugin or theme on your site.

Here are some steps you can take to troubleshoot this issue:

1. Check for Plugin Conflicts: Since disabling the Free and Pro plugins resolved the issue, it indicates that there might be a conflict with one of these plugins. You can follow our guide on checking for plugin conflicts to identify the conflicting plugin.

2. JavaScript Errors: You can further investigate JavaScript-related errors by using the Developer Tools Console in your browser. To open it in Chrome, navigate to More Tools → Developer Tools, then click on the Console tab. This will help you identify any additional errors that may be affecting the Editor’s performance.
   
   

3. Firewall Settings: If you are using a firewall, ensure that it is not blocking any necessary files for Rank Math. You can check if Rank Math is being blocked and whitelist it if necessary.

4. Server Resources: Sometimes, slow performance can be due to insufficient server resources. Check your server settings and ensure they meet the recommended values for PHP max input variables, time limit, memory limit, and input time.

If you continue to experience issues after trying these steps, please reply to this ticket, and a human agent from the Rank Math Support team will assist you further.

Thank you for your patience, and we hope to resolve this issue quickly!
