Divi Builder Timeout and Unknown Error

Typically, error appears as shown below:

An unknown error has occurred. Please try again later

Sometimes Divi timeout error occurs while loading the builder or opening a module.

The error dialog does hint that the issue might be due to a third-party plugin that’s causing the conflict.

Today, let us see the steps followed by our support techs to resolve Divi Builder Timeout Error

The solution is to try disabling one plugin at a time and see if the builder loads properly.

Check for the PHP Limits, PHP version, Cache, Plugin and child theme conflicts.

Check the Divi Support center page in the WordPress Dashboard and when I did, I saw two red dots that suggested to upgrade the PHP version and provide permission for the webserver user to write into the wp-content directory.

Then, check the write permission for the wp-content directory.

To confirm, I enabled WordPress Debug.

Edit wp-config.php file.

define( 'WP_DEBUG', false);

to

define( 'WP_DEBUG', true);

Now I see the detailed error in the web server log file.

2020/01/08 10:48:49 [error] 18271#18271: *2598 FastCGI sent in stderr: "PHP message: .../cache/Directory.php:65 ET_Core_Cache_Directory::_initialize():
Unable to write to filesystem. Please ensure that PHP has write access to one of the following directories:

- WP_CONTENT_DIR
- wp_upload_dir()
- ET_CORE_CACHE_DIR" while reading response header from upstream, client:

#chown <username>:nginx wp-content/
#chmod 775 wp-content

Now it started working like a charm!

Divi requires write permission to the wp-content directory, so I just navigated to the wp-content directory and saw a directory named et-cache created.

For performance enhancement, Divi introduces static CSS file generation which is cached in the et-cache folder.
