XenForo 1.1.4 upgrade is repeatedly failing for Admins Forum. Error: "Line 18: Template Syntax Error". It's locked in upgrade. I cannot use the forum unless I upgrade. But I cannot upgrade. I didn't take a backup either, which is my biggest ever mistake! I suppose I wasn't expecting something to go wrong. SILLY ME! Could someone please offer advise? If that's even possible for this. Because my biggest fear here is: Start all over again. No thanks.
