    I think there's a problem with the theme/skinning of the admin side of 3.5. Ever since the upgrade I keep getting the error: 

    Server cannot modify cookies after HTTP headers have been sent

    This seems to be happening because it's trying to find various css files which I've listed below, but they are not present in the patch or my original 3.2 installation. Any idea how to stop these? I tried changing the css to remove the images but how do I stop it from looking for the css file that's, not there, add a blank one?

    Hi SelArom,

    Do you have any controls that use these files? Default2006 is a skin of the Editor. We are not sure which controls exactly need these files - it might be some of your controls. We have tried to use Blank Project and see if there are any controls, but to no avail.

    Best wishes,
