CMS admin css not loading

[cmshelpneeded]

We are having problems viewing the cms admin. The login page looks right but all the internal admin pages are not loading with the css, ie the links just go down the page then the content, etc. Does anyone know why this is happening and how to fix it?

Can you post a screen shot? Have you upgraded CMSMS recently? (If so try clearing cache).

I deleted the frontendusers module and that fixed it. I'm not sure why though.
