Every time I log out of the forum I cannot get back in unless I hit the "forgot password" button and re-set my password, even if it's to the same password that I already have. I always delete browsing history etc. on exit from Chrome and wondered if that's the problem and if there is a get-a-round?.... otherwise I guess I'll just need to keep re-setting my password - which seems a little lame!?
I had a similar issue earlier this evening and eventually realised that the issue was I was already logged in elsewhere on a (Edge) browser tab I could not see. (It got lost on a different window which was hidden).
Not sure that's my issue but Nabble Support offered no support at all - basically saying I needed to sort it myself! Still get the problem, sometimes I can log in - by re-setting my password, sometimes it just doesn't want to play ball at all!
