I am trying to edit our website home page using Cornerstone, but I am not able to. The page preview hangs, and nothing loads.
On the live website, I re-created the home page but I still had the same problem.
Then we created a stage server and started testing.
We found out that there is a conflict between Cornerstone and Complianz Privacy Suite (GDPR/CCPA) premium. If Complianz Privacy Suite (GDPR/CCPA) premium is deactivated, the issue disappears.
Disabling Complianz does help to solve the issue. However, we need to keep the plugin active to make the website compliant. The issue is caused by a specific Integration under Complianz -> Integrations -> Services / Plugins .
Because our home page has an embedded video from YouTube, I resolved the issue by turning off YouTube under Complianz -> Integrations -> Services. This is a workaround, not the solution.
