Create or edit articles not possible anymore
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.
