This must be a bug - and potentially a serious one.
I've just installed v2.3.2 and created an admin user when I installed, then I created a second admin user and now, regardless of which email and password I use to log in with I'm always logged in as the new (2nd) user.
What's going on? I've cleared session cookies and even switched browser but still only ever log on as the last created user (2 of 2 in this case)!
Need someone to offer an explanation otherwise I'll have to stick with 2.3.1
Cheers,
Rich
