This troubleshooting guide may require that you make server-side changes to your website. If you are uncomfortable making those changes, you will have to contact your hosting provider for assistance.
Several things may cause the Visual Builder not to load, and often, no error is attached to indicate the problem. Below are a few things that can cause issues with the Visual Builder initialization.
PHP Limits
Each 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 128M
post_max_size 64M
max_execution_time 120
upload_max_filesize 64M
max_input_time 60
max_input_vars 1000
PHP Version
We recommend running the PHP 8+ version (or at least PHP 7.4). Most hosting providers have the 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.
Cache
Caching is a very complex system that can easily cause conflicts between scripts. Always clear all your caches once a plugin, theme, or the WordPress core has been updated.
Cache may include:
Browser Cache (Tutorial 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 after the plugins are 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 creating the conflict.
The latest version
Ensure you are running the latest version of Divi, Extra, or the Divi Builder plugin (depending on your set-up)
Consider switching to Divi Hosting

On Divi Hosting, PHP limits and PHP versions are already sufficient, so you don't need to worry about your server preventing the Visual Builder from loading. Plus, Divi Hosting comes with Divi pre-installed and activated automatically 😄
