I've just updated my site from ss2.4 to ss3.1 great improvements with the version 3 release!
I've moved in onto a dreamhost shared box and the only issue i'm finding is that i cannot insert images via the HTMLeditorfield
I have a feeling it could be the fileinfo module.
it was fileinfo, for anyone else encountering this problem initialize file info using
ssh into you home/username directory
then add custom configurations from there.
