got a real annoying problem that i've only just discovered. if i view my site in opera it appears as a totally unstyled page, as if there is no stylesheet at all.
every other browser i've tried (firefox, IE, chrome, safari) is fine. and the stylesheet is definitely there. i can even link to the stylesheet in opera and get it to display all the rules. it just won't act on them.
the only thing that i can think of is the fact that it has a .php extension rather than .css. but it's served with the correct header and mime-type is okay, and every other browser recognises it okay, so i can't see why that would be an issue.
i'm stumped. anyone had any similar problems with opera?
