Upgraded to latest version, added new License and site is no longer accessible

Please help - as this is a major problem. The entire site is down, and I cannot access the admin panel.

We had successfully upgraded www.yatesweb.com - and then I attempted to validate the licence.

The site immediately went offline.

URGENT help, please.

Hi There @mickyates

Thanks for writing in! A blank page usually means a PHP fatal error. You can enable WP_DEBUG on your wp-config.php file which is in the root of your WordPress installation and then revisit your site to see the actual error message.

You need to edit the line as follows.
define('WP_DEBUG', true);

One of the possible issue could be that you’re running an older version of PHP on your server. We recommend PHP version 5.6.x or higher to avoid incompatibility issues.

Let us know how it goes with more information.
Thanks!

The site is back.

We’re already running php 5.6.33 so no worries there.

Looking at the log files, it’s the plugins ‘cornerstone’ and ‘x-shortcodes’ that are causing the errors. We’ve disabled them both. As soon as you enable one or the other, the site goes down.

Hi there,

You may remove the x-shortcode plugin because all the shortcodes are not integrated with Cornerstone. Having both active on your site will cause an error.

If you are aiming to update X and Cornerstone to the latest version, it would be best to set up a staging site where you can do the update first so that your live site will remain intact.

You can find some information about setting up a staging site here:

If the issue persist when you try to update, please provide us with the link to the staging site and the admin and FTP details in a Secure Note (key icon below your reply) so that we can check it.
