Error with JoomSocial

Good afternoon:

I installed the plugin "Author Info box" but I´ve a problem with integration with JomSocial (version 3.1.0).
If I select in the plugin that I want to see the avatar from JomSocial, from the front end get the following error

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 'FROM WHERE = 835' at line 1 SQL=SELECT FROM WHERE = 835

The same thing happens if I select the web show or description by JomSocial.

How can I fix this?

Thank you very much for your help.

Regards, Marina
