Using both Safari 7.0.2 and Chrome 33.0.1750.117, I've tried to associate my Twitter username with my Keybase account, but I'm unable to submit the form after entering my username in the input field.
hey @barendt - I see your twitter account is proven now. Did you find a workaround or did this get fixed?
Keybase user molly is experiencing a similar issue – her identity verification is stuck at "pending". Safari 7.0.1.
I didn't find a workaround - I'm not sure how it got fixed.
If it helps, I can say that I was re-doing my Twitter verification, so I had already associated my Keybase account with my Twitter account at some point in the past.
I rewrote all these proof modals, and no one has been reporting this kind of thing for a while, so I'm assuming whatever caused this is fixed, by mistake.
