HTTP ERROR 500: Fatal Error after Cornerstone update

PHP Fatal error: Cannot redeclare class Cornerstone_Shortcode_Generator in /nas/content/live/dynamicis/wp-content/plugins/cornerstone/includes/classes/classic/builder/class-shortcode-generator.php on line 2585 .

Here’s a link to the site - http://dynamicimagingservice.com/ . Naturally, I restored to pre-update version.

Hello @Solidwebservice,

Thanks for asking and extremely sorry for the trouble you facing with Cornerstone. Since you have rolled back the website to earlier version, it’s difficult to debug the issue. In that regards here is what I can suggest and because it’s a live website, will it be possible for you to setup a staging server and then perform the update process? And if you face same or any other issue please share the login details in a secure note. That way we can resolve the problems (if any) without affecting the live website. You can refer our plugin and theme update guide for guidance:

Thanks.
