Cornerstone will not activate in my wordpress

I keep trying to activate cornerstone but keep getting this error:

Fatal error : Cannot redeclare cs_generate_data_attributes() (previously declared in /home/u15c4f8f/public_html/wp-content/plugins/tco-video-lock/functions/includes/cs/helpers.php:4) in /home/u15c4f8f/public_html/wp-content/plugins/cornerstone/includes/utility/helpers.php on line 256

Is there a way to get around this? thanks!

Hello Jordan,

Thanks for writing to us.

It seems that you have uploaded the Video Lock plugin multiple times. I would suggest you use your FTP and go access the files and rename the directory tco-video-lock to tco-video-lock-test

File path : wp-content/plugins/

If it doesn’t work for you, please share your details in a secure note. Please provide the following details

  • WordPress Login URL
  • Admin level username and password
  • FTP details

You can find the Secure Note button at the bottom of your posts


I’m not sure hot to access my FTP

Hello Jordan,

Please contact your hosting provider. They should be able to give you further assistance on how you can get the FTP details.

In the meantime, please go to the Plugins section and deactivate the Video Lock plugin.

Best Regards.
