navigation menu links in the forum not working

Hi there!.I'm encountering problem like this, I'm not directed to the right location from inside the forum, i mean if i click on the photos link in the navigation menu it should take to this fllowing link
http://192.168.0.87/LabSchool/Web/photo/all/10/1

but if click on the photos from inside forum page I'm directed to
http://192.168.0.87/LabSchool/Web/orca/photo/all/10/1


and the design of the photos page is distorted, the links are also not working properly here as well. Any idea???Cry
