Works on start page, but not on any sub pages
I'm working on a big website and the current task is to get the new design in place. We are using a previous website, that is similar, as base and working from there. Now, a few days into the work I realized I hadn't taken IE7 and 8 into account so I set out to fix this. I've been using border-radius and box-shadow alot, so I thought I'd implement CSS3 PIE. It works great, except for one thing... It only wants to work on one page: the start page. As you can see here: the menu and several other elements have a border-radius and/or a box-shadow. Everything gets this from CSS (except the white menu-buttons as for ie7 and 8 I decided to use images instead). The header, the menu and the white bar just below the menu are included (along with the <head>-tag and all the css-files it calls) in a template, which is included on every single page on the entire website. So, the CSS and PIE should work everywhere, right? Wrong. It only works on this single page. Check this page for example:
All rounded corners and shadows are gone, except for the menu-buttons which are images (although in IE8 even these seem to disappear! what the hell?), but nothing in the CSS is different as it calls the exact same CSS files and exact same markup for the menu and header! Does ANYONE have any clue as to what might cause this? My brain is having a bit of a meltdown over this.
Also, some margins here and there are off on the subpages as well in IE7 only, like the margin below the menu.
Hope you don't mind that the site is in Swedish, shouldn't be a problem I think.
Any and all helt is greatly appreciated!
