I just encountered strange problems when I try to reply to threads.
First of all, I could use quick reply without any buttons, it works and that's how I replied.
But, if I click on button to reply normally, page hangs with rotating image:
Advanced editor doesn't open. Even when I click on quick reply, it still hangs page. But, I could use quick reply and I answered, but without buttons (icons). Maybe it's related with new mod vBEditorTabs
