My client (Joomla User: Manager) cannot insert Youtube Videos with the JCE media manager. When using backend the video doesn't show anymore after saving. although it seems normal when inserting it with the media manager (before saving). In frontend there is the following error after saving: 403 Forbidden - Access to this resource on the server is denied!
The logs do not really help me. I attached them.
When logged in as Super User everything works 100%. Super User, Frontend user and backend manager use the same JCE profile.
Would you know what could be the reason behind this. Let me know what you need from me to investigate this issue, please!
