I have actually done 777 on the tmp directory, it did let me do that. There are also cached files in that directory, only they are directly under that dir, not in sub-directories. Does that matter? It is a reseller account, and I have other accounts with Silverstripe on it where everything works fine. This site used to work as well.. Not sure what I have done.
I do have a support chat with my host, but if I can do 777 on the tmp directory then I should have write access, shouldn't I?
Thanks again
