Hi,
I just upgraded from the second 1.4 release candidate and I'm getting a wierd problem with both my default, homebrew theme and the official 1.4 Professional theme.
Everything seems to be working OK, but in the upper left corner, above what is fed from the normal header.thtml on an otherwise blank line is this:
?>
That's it, just the PHP closing tag. I would think that it's just my theme that needs tweaking, but it does it with the professional theme, and both themes were fine with the release candidate.
EDIT: I should note that it does this with either IE or Firefox.
