Okay, uploaded all files/folders in that 1.6.4 package and ran the upgrader. Now stuck @ "Repairing Database Sequences
Performing necessary upgrade queries..."
Forums are completely inaccessible at this point
Are you absolutely sure you uploaded all the files and that they overwrote the existing ones? Because no-one else is having this problem. Your MySQL version is fine too I think.
Yeah, I decided to delete the /install folder completely and according to MyBB version check I'm up to date. itsamystery.gif
