File permission error. (File permission page makes error)

[MrPhil]

Where did all this discussion about "tmp" directories come from? The error message very clearly shows that it's trying to an is_dir() on /customers/b/f/a/arpegi.be/httpd.www/.. which is out of the allowed range of directories (it would be one above /, or /customers/b/f/a/arpegi.be/). So, the question is why is_dir("..")? Something has got to be misconfigured in SMF.
