Cornerstone Error: The preview was unresponsive after loading. This is most often related to a plugin conflict or aggressive page cacheing

Hello, I can no longer edit certain pages in cornerstone.

I get this error: The preview was unresponsive after loading. This is most often related to a plugin conflict or aggressive page cacheing.

I have tried all of the solutions that I found in the knowledge base to no avail.

Hi There,

Thank you for writing in, please clear all your caching plugins and deactivate it, see if that resolves the issue. If not while your caching plugins are deactivated please do a testing for a plugin conflict. You can do this by deactivating all third-party plugins, and see if the problem remains. If it’s fixed, you’ll know a plugin caused the problem, and you can narrow down which one by reactivating them one at a time.

@imhat I see that your MYSQL version is 5.5.59, please contact your hosting and see if you can upgrade that to 5.6 or higher. I also notice that the issue is only happening on that specific page, try to remove the custom JS you have on that page.

@AnnieBeebe If none of the solutions provided above works for you. Please create a new thread and provide us login credentials in a secure note on your own thread.

Let us know how it goes,
Cheers!

I contacted my host support, they said there were no updates for MYSQL yet. They upgraded PHP to 7.1 and then the tech was able to use cornerstone for the homepage on his end. I still cannot. Can you try on your end and let me know if it works for you now? Is there anything else I can try? Thanks!

Hi There,

I have tested loading your homepage and I see the following error on your console log.

The preview booted, but never requested the loader be removed

Could you please try increasing your PHP max script execution time to 300 and test again to see if that helps. Also try deleting Cornerstone plugin and re-install it again by head over to X -> Validation section (wait for few seconds to install it automatically).

I have removed your custom JS added to the homepage temporarily. When you’re adding JS code, you can ignore <script> </script> tags.

<script>(function(d, s, id) {
  var js, fjs = d.getElementsByTagName(s)[0];
  if (d.getElementById(id)) return;
  js = d.createElement(s); js.id = id;
  js.src = "//connect.facebook.net/en_US/sdk.js#xfbml=1&version=v2.9";
  fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));</script>

Let us know how it goes.
Thanks!
