Given destination is not writeable

Greetings -- just started to get this error. Everything has worked fine in the past but all of a sudden it just stopped. I already looked at another post that mentions the theme_uploads directory in the archive directory needs to be writeable (and it is) Any other thoughts?

CentOS Linux 5.4
MySQL version 5.1.45
PHP Version 5.3.2

We can close this now -- Sorry -- figured it out...
