Cornerstone "The Preview Was Unresponsive After Loading ..." Error

Hi, i just updated our site to the newest version of X/Cornerstone after several months (summer 2017?) and nothing seems to be working any longer. I am getting the following message when I go into a page in Cornerstone. Can you please direct me to what I need to do to trouble shoot this issue. I am not a web developer so if you could point me to the clearest and simplest approach it would be much appreciated :slight_smile:

Hi There,

Here is few points that can be look on to avoid this issue.

Please check for the following first:

  1. Ensure everything is up to date according to our version compatibility list at https://theme.co/apex/forum/t/troubleshooting-version-compatibility/195. Please follow the best practices when updating your theme and plugins. See https://theme.co/apex/forum/t/setup-updating-your-themes-and-plugins/62 for more details.

  2. Clear all caches including browser cache then deactivate your caching plugins and other optimization plugins.

  3. If you’re using a CDN, please clear the CDN’s cache and disable optimization services.

  4. Test for a plugin conflict. You can do this by deactivating all third party plugins, and seeing 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.

  5. Remove custom CSS, Javascript and templates.

  6. Reset your htaccess file by renaming it to .htaccess-bak. Then in WP Admin Menu, go to Settings > Permalinks and just click the Save Changes button.

  7. Contact your host to increase your allocated memory or do it yourself by adding this code in your wp-config.php

    define( ‘WP_MEMORY_LIMIT’, ‘256M’ );
    define( ‘WP_MAX_MEMORY_LIMIT’, ‘512M’ );

In case the issue persists, would you mind providing us with login credentials so we can take a closer look? Please provide following information:

    All the best!
