Rails 3.0 Fleximage Error Errno::EACCES

Hi,

I'm using Fleximage on my website so users can upload avatars. I recently upgraded to Rails 3.0 and switched host to slicehost.com. I successfully installed imagemagick and the gems rmagick and fleximage. Everything seems to be working fine except when I try to edit my account and upload an avatar. After selecting an avatar and click the update account button I get the following error:

Errno::EACCES (Permission denied - /root/public_html/biomixr/tmp/fleximage):   app/controllers/accounts_controller.rb:103:in `update'

Now I've been stumped on this. I looked at my permissions for /root/public_html/biomixr/tmp and they are 755.

I in turn ran the command: mkdir /root/public_html/biomixr/tmp/fleximage to create the fleximage folder.

I then tried to upload an avatar again and this is the error I get next:

Errno::EACCES (Permission denied - /root/public_html/biomixr/tmp/fleximage/1314277489_47901):   app/controllers/accounts_controller.rb:103:in `update'

So I am really confused on what is going on.

I would appreciate any help.

Thank you.
