CONFIRMED! This must have been broken by my upgrade to the latest XenForo version. I'll get it fixed!
All done! There's probably an orphan account called brianoflondon_s that you can delete if you want. I've now associated this account with my SQRL ID which I'm using on my MacBook via Wine and on iPhone via Jeff's client.Brian: XenForo's recent jump to v2.1 broke MANY 3rd-party addons, including SQRL. But it's back up and working now. So you should be able to easily associate your SQRL ID with your current account! And welcome. For some reason I immediately recognized your avatar image... perhaps from Twitter.
Ken, where did you get the Wine you used on macOS. Any special settings/configurations needed? I would like very much to get SQRL on my Mac. I tried winehq-stable-4.0.pkg with little luck.I was able to log in normally and then successfully associated my sqrl ID - using Steve's client under Wine on macOS
