Critical Error Wordpress with Divi Theme

Hey Stephen,

This indicates that an error has occurred in the site's PHP code. There can be various causes, such as hosting memory limits being reached or an error in a plugin.

You should have been sent an email to the admin email address configured on the site. If you check this email it should have the full error message (including affected file and line number) associated with the error. If you share that here we should be able to point you in the direction of a solution. If you can't find the email / error message, you can also get the error message by enabling the WordPress debug.log:

Once enabled, trigger the error and check for the error message in the /wp-content/debug.log file. Again share it here for interpretation.

An alternative approach would be to disable unnecessary plugins (which might get you back below any memory limit being hit) and if the issue persists, disable plugins one at a time to find the one with the issue. Then work with the plugin author to get a fix (note that they'll likely want to get the error message as described above).
