SQL Error when i try to display a group in front-end

Hi, I have a problem, I just start using Groups feature of Easysocial but i have an sql error when i try to display my group in frontend...

1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1 SQL=SELECT title, alias, description FROM tmwfs_social_clusters_categories WHERE type = 'event' AND id =

ID=nothing!

I also tried to disable the events globally, and in the group category options but nothing change.. any suggestions?

Thanks
