Oh, how I totally screwed up the experience for new users.
When doing a reorganization of the source code I forgot to hook a lot of the user actions when setting up jsiBitBot for the first time to the appropriate code blocks. This resulted in a nasty error dialog when testing the captcha settings and the bots didn’t work at all.
Thanks a lot to user Lauri for having the patience to report the error and retest my poor attempts at fixing it.
As usual you can download jsiBitBot here.
