Look at this picture: (when a user is not log in in the board). This is ok

Now Look at this other image: (when a user is log in the board). This is wrong

(In the section of "polls" and "who is on line" at the botton of the page. Sorry it's in Spanish) I've got a blue background colour when It should be a white color. Only it happens in the portal with prosilver style and the user is log in the portal.
I tested a lot of things. I know where the problem is in the database. ( I've got a "old backup copy" and when I restaured this backup copy, it fixes the problem, but I lost a lot of datas: post, topics and users)
I tested to change ONLY the "phpbb_portal_config" from the "old backup copy" to the "now database" and it doesn't fix the problem
 . I'm very confused because the problem is not in the datas of the portal, but it happens only in the portal
 . I'm very confused because the problem is not in the datas of the portal, but it happens only in the portal   
 Thanks a lot

 . I've installed to fix the problem).

  but this information (I think)  not: the problem only happens with prosilver style ( My portal has three diferent styles. The users can choose: prosilver, subsilver2 and BF_Vista style (is based on subsilver2). The "sub2" and "BF" work properly, but prosilver style NOT ¿¿??
