Hi, After domain change, I have all working nicely except /admin/customize/embedding it returns 500 error and this error in log is related I think: `NoMethodError (undefined method 'path_whitelist' for #) /var/www/discourse/vendor/bundle/ruby/2.6.0/gems/activemodel-6.0.3.1/lib/active_model/attribute_methods.rb:43` I was using embedding for the Ghost blog only. How can I remove all embeddings manually? (hope it will fix this issue) Or is there a better way to fix this? Thank you! ---

Solved. The problem was not in domain change, but in version change to stable from tests-passed. When I returned to tests-passed - I was able to get to the _/admin/customize/embedding_ again. ---
