Despite of this error, the reply gets posted. It only displays after I refresh the page.
I've tried disabling all the addons I've installed but that doesn't seem to solve the issue.
What could I possibly try to solve this issue?
I'm using XenForo 1.1.3 with XenAtendo, XenPorta, [bd] Tag Me and TaigaChat addons.
There are few outdated templates.
