Invalid token on almost every login

Dear support,

We face an issue for some months now. We tried many things and the problem might lye with the EasySocial and EasyBlog modules.

We use the EasySocial menu module (home page) and the EasyBlog welcome module (on all the other pages) in order to login to the site. If you logout and try to login again with your user we hit the "invalid token" error.

Any ideas?

Regards,
