Note: This troubleshooting guide may require that you make server-side changes to your website. If you are not comfortable making those changes, you will need to contact your hosting provider for assistance.
The Divi Builder Timeout Error occurs when the builder fails to load because of an unknown error. Listed below are a few things that can cause this error to occur.
PHP Limits
Each website environment is set up differently and hosting providers can limit PHP directives value for various reasons.
Here is a list of configuration directives that are optimal for running a WordPress website:
memory_limit 256M
post_max_size 128M
max_execution_time 300
upload_max_filesize 64M
max_input_time 600
max_input_vars 6000
PHP Version
We recommend running the PHP 7.0+ version (or at least PHP 5.6). Most hosting providers have an option to change the PHP version from their cPanel, however, if that is not the case you can always reach out to them and they should be able to take care of it for you.
Note: Most hosting providers can assist you with adjusting your PHP Limits
Cache
Caching is a very complex set of systems that can easily cause conflicts between scripts. Make sure to always clear all your caches once a plugin, theme and the WordPress core has been updated.
Cache may include:
Browser Cache (Tutorials on clearing your browser cache)
Plugin Cache
CDN Cache
Server-side Cache
Plugin(s) Conflict
Sometimes plugins can conflict with a theme or with each other.
Disable all your plugins and see if the problem persists. If everything is working once the plugins were disabled it means there's a conflict with a plugin or maybe even a set of plugins.
Enable the plugins one by one to identify the one that is creating the conflict.
Child Theme Conflict
To test for a child theme conflict you can temporarily disable the child theme by going to Appearance > Themes and enabling Divi (the parent theme).
The latest version
Make sure that you are running the latest version of Divi, Extra or the Divi Builder plugin.
