Elementor or other page builder does not load
Page builder plugins like Elementor, Divi, Avada's Fusion Builder or others can be quite resource-intensive. You may find that after activating WP Rocket, your page builder stops loading when you go to edit a page. This is usually not a direct conflict with WP Rocket, but is due to a lack of resources for your site.
Symptoms of the problem
- When editing a page, the Elementor (or page builder) editor doesn't finish loading
- In your browser's developer tools you may see a 500 error on the admin-ajax request from Elementor:
Check for memory errors
- Check the PHP error logs for your site, or enable WP_DEBUG and see if you are getting fatal PHP errors related to memory
- Elementor has its own built-in logging in the System Info tab which will reveal errors:
Solution
Increase the amount of PHP memory for your site, which you can do by following this guide:
https://docs.wp-rocket.me/article/128-increase-php-memory-limit-in-wordpress
Keep increasing the memory limit gradually until the problem is resolved.
Please also see Elementor's own documentation for this issue.
