Same issue in "Safari Version 14.0 (15610.1.28.1.9, 15610)". Though categories became a problem after adding three categories, the auto search went blank (screenshot attached)!

Same issue as well, using "Chrome Version 85.0.4183.121 (Official Build) (64-bit)" on MacOS 10.15.6 (19G2021).

Unable to login. Says incorrect password and I know the password I'm using is correct! I say what happened (since it says my account doesn't exist) was that it was a Wiki export and not a SQL export.

Was working in 2014 with the public wiki but Comm wiki hasn't worked during my terms on Comm.
