Dear Forum,
I am using this plugin since some days:
The Trew Knowledge GDPR WP plugin
Somehow it seems there is a clash with Cornerstone. Once the plugin is active, cornerstone is not displaing any section.
Unfortunately in the dev console there are no real errors, but I found out that once the GDPR WP plugin is deactivated cornerstone is working again. Maybe this is not related to you but it would be really great if you could check?
Thanks in advance!
