When Xstore theme is activated and Gravity Forms is activated, we were unable to edit pages. It would spin for a bit and then come back with
This page isn’t working
XXXXXXXX.com didn’t send any data.
ERR_EMPTY_RESPONSE
This only affected pages. We could still edit posts and Custom Post Type posts.
If we deactivate Gravity Forms, we are able to edit pages.
If we kept Gravity Forms activated and then deactivated our XStore child theme and reverted back to the stock XStore theme, the issue continued to happen. So the issue appears to happen when any of the Xstore parent or child theme is activated and when Gravity Forms is activated.
If we deactivated XStore parent theme and activated Twenty Seventeen theme, and also keep Gravity Forms activated, we are able to edit pages just fine.
The conflict is between XStore and Gravity Forms. Nothing is logged in the php error log.
Extending the PHP Max Execution time to 200 allowed the pages to finally be able to be edited, but it takes almost 30 seconds for the pages to load editor.
We deactivated all plugins and turned them back on 1 by 1 to determine that Gravity Forms was causing XStore to not load pages. We have Gravity Forms running successfully on many other websites running different themes.
We noticed several other people in the support forums reporting similar issues over the past week – no one reported Gravity Forms, so I am passing this info on to you. We are running the latest version of Gravity Forms – 2.6.3
