Some of my Authors (strangely not all of them) are not able to add new articles or edit theirs (they have the same rights/permission, meaning all are authors). They get a white page which contains the error i'll attach. I must admit that i am not yet able to fully understand the problem/error message. It just seems to have something to do with either Jcomments and / or community polls. So i'll ask wherever it seems possible that someone can help me. Any idea where to look?
Infos: All extensions and also Joomla is up to date, i tried deleting cache, different browsers, logging in and out, deinstalled and reinstalled Jcomments, but that didn't help.
