Can no longer activate Cornerstone

[ARGEntur]

Hello

I am getting error messages on the drwaidmann.at site regarding Cornerstone and I can no longer activate the plugin. I receive the following error message.

The plugin cannot be activated because it generates a fatal error.
Fatal error:
Cannot redeclare cs_generate_data_attributes() (previously declared in /u/htdocs/waidmann/web/wp-content/plugins/tco-video-lock/functions/includes/cs/helpers.php:4) in /u/htdocs/waidmann/web/wp-content/plugins/cornerstone-1/includes/utility/helpers.php on line 295

Hi @ARGEntur,

Thanks for reaching out.
It seems there might be any conflict between the version of Cornerstone and the X version. I would suggest you follow the below steps

1. Delete the existing Cornerstone
2. After the X theme is updated, use the link in the dashboard to automatically install the Cornerstone. It will be in the latest version.

If that does not help, there might be other reasons behind your issue. I would like to suggest troubleshooting the following common issue to help us to recognize the reason.

1. Theme Related Issue
2. Plugin Conflict
3. Theme Update related issue
4. CSS/JS Customization
5. Disabling Cache
6. Disabling CDN

If none of the above help, please copy your live site to a staging server so we could troubleshoot freely without breaking your live site.
And give us access to the secure note including:

– WordPress Site URL & Login URL
– WordPress Admin username/password

To create a secure note, click the key icon underneath any of your posts.

Thanks

Hi @ARGEntur,

I have investigated it and found that the plugin named Video Lock is creating the problem. I deactivated the plugin and reinstalled the Cornerstone by following the given steps, and it worked. Later I activated the Video Lock plugin and everything is working fine now.

Thanks
