Hi,
Cornerstone was deactivated and now there is a fatal error - Fatal error: Cannot redeclare cs_generate_data_attributes() (previously declared in /home/psbfazvd/public_html/wp-content/plugins/tco-video-lock/functions/includes/cs/helpers.php:4) in /home/psbfazvd/public_html/wp-content/plugins/cornerstone/includes/utility/helpers.php on line 144
Ive tried to reinstall but it is still not successful. Can this be fixed?
Thanks
Hey,
You can check your PHP version and ask your host provider to update it to the latest version.
I get the same problem.
Also updated the php-Versions on my server. I tried with 5.4, 5.6 and 7.1
With any version I get the same error.
Hi guys,
Please start a new thread about this issue and provide your site’s URL, admin, and FTP login credentials in a secure note.
The error means there are multiple active plugins, if you’re on Pro then please delete cornerstone plugin. It doesn’t need cornerstone 
Thanks!
