Why do I get Divi builder timeout warning?

This problem sometimes occurs when using the Divi WordPress theme. If you try and edit a post or a page on your website using the Divi or Visual builder you might see the warning “Divi Builder Timeout” that stops you from using the editor.

The problem occurs when the Divi builder reaches a pre-set limit applied to the Apache service. To fix the issue, the limit needs to be raised. To do that, add the following lines to the website’s .htaccess file:

<IfModule mod_substitute.c>
SubstituteMaxLineLength 10M
</IfModule>
