Cornerstone is not loading properly; "...preview was unresponsive after loading..."

[kmaweb]

This seems to be a recurring theme with Cornerstone and I’d like to know how to fix it. We’re editing our website on two different computers. One one computer it’s working fine and on the other we pretty much constantly are getting ‘The Preview was unresponsive after loading. This is most often related to a plugin conflict or aggressive page cacheing’. We currently have no plugins installed and nothing is being cached. What’s the solution to this issue?

Hi There,

Thanks for writing in! Most probably it could be a PHP memory related issue. Could you please try following the solutions below and see if that helps.

1. Try re-generating your permalink settings and see if the issue is related to your .htaccess file. Check your permalink settings (General -> Permalinks) and set Postname save changes to re-create your .htaccess file.
2. Then the next possible issue would be that you’re running out of your memory. You can try increasing your PHP Memory limit. You can do this by editing your wp-config.php file which can be located under the root of your WordPress installation. Add the following lines into that file.

define( 'WP_MEMORY_LIMIT', '512M' );
define( 'WP_MAX_MEMORY_LIMIT', '512M' );

You can add it before the line
/*That's all, stop editing! Happy Blogging. */
3. Make sure that you’re running at least PHP v5.6.x or later to avoid any WordPress related incompatibility issues. If you’re not sure what your server configurations and settings are, install a plugin like WP-Serverinfo (https://wordpress.org/plugins/wp-serverinfo/) and check your server info by head over to Dashboard -> WP Serverinfo area.
4. Check your PHP Max Execution Time and set it for 300 for optimal usage.

Let us know how it goes.
Thank you.
