Cornerstone Whitescreen on update

Support
#1

Hi, I recently updated a dev site to the latest version of Wordpress (4.9.6), also updated X to 6.1.6, and updated the Cornerstone plug-in to 3.1.6. As far as I know they are all running the latest versions, however whenever I try to activate Cornerstone or edit a page in Cornerstone I just get a white screen.

Also the Contact Form 7 plugin which was packaged with X completely knocks the site over, so I’ve had to disable it. There appears to be some kind of conflict, but after hours or trial and error, I can’t get it to work. Can anyone help me out?

Hi,

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 and maximum execution time or do it yourself by adding this code in your wp-config.php

set_time_limit(300);
define( 'WP_MEMORY_LIMIT', '256M' );
define( 'WP_MAX_MEMORY_LIMIT', '512M' );

  1. Check if you have at least php version 5.6 installed in your server

  2. Set wp debug in your `wp-config.php file to true and check what error you are getting.

define('WP_DEBUG', true);

Thanks.
