I have a problem with Content Filtering. I have URL's being blocked even though it does not look like these are categorized under any blocked category. For example, the URL http://inschool.gr/ is blocked even though it is in the Education category which is not blocked.
Additionally, it looks like the URL is still blocked even after adding it to the Allowed URL list.
I have no Group Policies blocking content and the URL in question is not in the Blocked URL list.
Any idea what I could be missing?
