Error of Easyblog Groups For Jomsocial

Hello,

I've updated my site to the lastest version but there some problems with the plugin Easyblog Groups For Jomsocial.

Every time someone submits a comment on a blog, it shows "Internal Server Error" and get stucked. Actually the comment is saved but the user doesn't know and he may keep click several times and then, there are several comments.

You can have a test here:

If I re-edit the blog and move it from a group to any Easyblog category, then nothing wrong.

Please give me a hand.

Thanks!
