Thread:Extension talk:GoogleLogin/Internal error " WEBROOT /mediawiki-1.22.2/includes/htmlform/HTMLForm.php: HTMLForm: no submit callback provided. Use setSubmitCallback() to set one."

Hello,

I'm looking around for the possibility to use Google Login via OAuth and come to this great MW extension. So far so good. The documentation and configuration sample is very good but after setting everythin up I can't login an existing or create a new user via the Special Page GoogleLogin. Everytime I get the Internal error on my MW Special page after successfully login at Google:

[6893f829] /wiki/index.php?title=Special:GoogleLogin/Create Exception from line 464 of //mediawiki-1.22.2/includes/htmlform/HTMLForm.php: HTMLForm: no submit callback provided. Use setSubmitCallback to set one. Backtrace:

How can I fix this issue?
