I figured it out, the css is not perfectly formatted. It has 10 places it's calling like this:
Code:
"../../cpstyles/eti_mavi-i_Admincp/IMAGE NAME.gif"
and it should only be calling like this:
And it's calling for an image in another admin theme:
Code:
../../cpstyles/vBulletin_3_Default/merge_conflict_bg.png
when it could have easily been copied to his new theme.
It's just not very clean css
