tried logging in normally (not w/ Facebook) on mobile and couldn't due to this. managed to login through teksyndicate.com
I have similar issues. I have to login through teksyndicate.com (rather than from the forum) but I have to switch the browser to request desktop site or it won't work.
I'm assuming the Web devs broke something. I feel like the forum login shouldn't be touching Facebook anyway though...
I am having even weirder issues on the phone. When logging in, it keeps typing every letter again.
Here's what happens when I try to enter my username :
Press C -> C
Press a -> CCa
Press p -> CCaCap
press t -> CCaCapCapt
press a ->CCaCapCaptCapta
press i -> CCaCapCaptCaptaCaptai
press n -> CCaCapCaptCaptaCaptaiCaptain
backspace doesn't do anything, but selecting most of the word does allow me to delete it, at which point everything starts to work as it should.
I can then add the rest of the name just fine and there are no issues when entering my password either.
HTC One M8 running Cyanogenmod 12 (stripped down 12.1-20150726-nightly without Gapps to be precise) , Firefox 43.0 with Ghostery and HTTPS Everywhere installed. Super stable phone and ROM, not a single hiccup since I installed it in late July.
Moved to new bug section for now in case this turns out to be a real issue.
