Can not add nor save any lore texts since this morning

Yesterday everything worked fine.

Since this morning I can not add any new lore texts or rework any existing lore texts in my Garou Chronicles:Ironwood world. The texts show up in the edit window, but when I hit save it reverts back to the old text or disappears completely. It also does not safe when it is a newly added entry. I also get kicked from F&F when I try to sort Lore Entries manually and I get redirected to the Overviw Page afterwards. I use Browser (Opera and Mozilla, I deinstalled both and reinstalled both, problem persists, I also restarted my laptop 2 times).
