I can't seem to remove labels from a page, I get an error. Any ideas?

Dear,

I have a similar issue, but here labels do not contain any special characters. See screenshot with very vague error message:

Solution: removing labels triggers a specific request, which was blocked by security at Data Center level.

Have you tried clearing your browser's cache or using a different browser?  Are other users having the same issue?  

What are you seeing in the confluence logs?  I am assuming that there is additional information there.

Thanks for the follow-up. In the meantime, issue has been solved: removing labels triggers a request, which was blocked by our Security Team. In this case, what is surprising is that this labels feature is using a "side" request, like 3rd party plugins could do.
