I downloaded the ubbthreads-7-7-1.zip file from the Member Area last night, it shows 29/01/2019 9:07 AM. I followed the 7 Upgrade Guide
twice and the resulting error occurred each time. I've restored my directory prior to the procedures and will attempt another round. Is it possible to do a clean install and somehow patch in the database? I'm able to do clean installations with no error. It's the upgrade that's causing a loop.
