WordPress database error… again

HI Guys! Just want to know if anyone can tell me how to solve this. When I activate the permalink option I get this message:

WordPress database 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 ” at line 1]
SELECT category_nicename FROM wp_categories WHERE cat_ID=

I have read that using a plug in could be the reason. I’m using the coffee2code category image plug in and the yugatech date image plug in.

For the permalink option I’m using :
/index.php/%year%/%monthnum%/%day%/%postname%/

My website is abiertoalanochecer.com (it’s in spanish). I suspect the fact that the wordpress directory is inside http://www.abiertoalanochecer.com/wordpress/
and not under the root directory has something to do with it. Does anyone can tell me how to solve it…??

thanxs in advance…!
