I thought I’d quickly write this up for anyone who may have lost all their ESO addon settings with the last patch. Your settings are still in the files, but due to a (supposedly) unintended bug, another list of settings has been added in there and the game is now reading blank settings, prompting you to need to set everything up again.
After I logged in and saw my UI all screwed up I promptly threw my computer out the window, but after I cooled off a bit and retrieved it I did some research and found out how to get my settings back.
