Error loading cornerstone :(

“Greetings, The preview was unresponsive after loading. This is most often related to a plugin conflict or aggressive page cacheing.”

I’ve tried to disable WP Super cache, wordfence, and other plugins but the issue persist. Any suggestion?

Hi There,

Thanks for writing in! Could you please try following the guidelines below and see if that helps.

• If you’re using a caching plugin, make sure to purge all server cache and disable it until you do the testing.
• 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.
• Check your PHP Max Execution Time and set it for 300 for optimal usage.
• Check your permalink settings (General -> Permalinks) and set Postname save changes to re-create your .htaccess file.
• If you’re using a service like CloudFlare, make sure to disable auto minification. For more information, please check this guide (https://xthemetips.com/using-cloudflare-rocket-loader-with-x-pro-and-x5/928/).

Also 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', '256M' );
define( 'WP_MAX_MEMORY_LIMIT', '512M' );

You can add it before the line
/*That's all, stop editing! Happy Blogging. */
