Website fatal error

[macvink]

Can you please help me? The following website is offline because of an fatal error and i don’t know what to do about it.

Fatal error : Cannot declare class Cornerstone_Shortcode_Preserver, because the name is already in use in /home/cburg/domains/cburgcollege.nl/public_html/wp-content/themes/pro/cornerstone/includes/classes/classic/utility/class-shortcode-preserver.php on line 8

Hi @macvink,

Unfortunately, the admin login URL is also not accessible due to the error. I would suggest you remove the existing installed theme through FTP/CPanel and upload the latest version by downloading it from your Themeco Account.

Hope it helps.
Thanks
