Since about two weeks I can't post anymore to our forum - not this one! Odoo switches to my profile page and a error massage says:

Please enter a valid email address in order to receive notifications from answers or comments.

In the log file I found the following:

2014-12-06 14:36:16,657 1020 INFO jeema-sol werkzeug: 10.10.0.1 - - [06/Dec/2014 14:36:16] "GET /en_US/forum/help-1/user/lucas-huber-8/edit?
email_required=1 HTTP/1.0" 200 -

Has anybody what could be wrong here? I can't find any validating section in odoo.

Or could it be a bug I did see many update in the forum module recently.
