Hi,

According to your description it seems that EasyBlog extension for JoomSEF is not installed. In that case, if you set Handling to JoomSEF Handler, it automatically chooses Component's Router as Active Handler if the component provides its own router.
In this case the SEF URL is also not stored in JoomSEF's database, because it's handled on-fly using Joomla's core functions and the component's router. There's unfortunately not much we can do about such URLs.

By setting Handling to JoomSEF Basic Rewriting, the SEF URL is created by JoomSEF as a simple concatenation of individual non-SEF URL values, which may be more suitable for you.

I believe we're already solving the JomSocial problem with you through e-mail communication.
