A few of my pages seem to be not working
 

Hi, some of the pages on my forum are weird, the memberlist page, the member profile pages are both weird,

(See example here: http://www.rs2underground.com/commun...rs/domino.html )

All other pages are O.K, and all my styles have the same problem..

Help =/

to fix this right click the parts that dont look right and place the images there in ur hosting or if u host it urself, so like if u clicked memberlist and u see the top gone? then u click usercp then it shows the theme, so what u do just goto the memberlist page and right click on memberlist and click viewimage then put the image from ur theme in that location =) hope i explained this enough for u to understand xD

Most likely caused by the modification you are using to rewrite your URL's.

Viewing the regular page works fine: http://www.rs2underground.com/commun...sername=domino

I used to have a mod like that, but completely uninstalled it from my admin cp.. Why is it still on?

Sometimes there is more to the mod than simply clicking a button to uninstall. Sometimes you had to upload other files, sometimes you needed to modify other files, sometimes you needed to add/change your htaccess file, etc. You need to go view the installation instructions and completely undo everything you did.
