drupal CDN module not altering URLs I'm using Drupal 7 on an Ubuntu VPS, I'm trying to setup CDN module with Rackspace cloud files. I'm using file conveyor and the whole setup going well. the only problem I have that Drupal CDN module not altering the files url to use the cdn urls. it still use local files. 
- the files already synced to rackspace.
- file conveyor working fine.
- Drupal CDN configured correctly  and it show me that it sees file conveyor working and it's sees the sync file database.


more details about the issue: I'm using multisite setup and I'm using file conveyor with the public files folder.


Any Advice? Thanks
I suspect you have a setting or two wrong.  On admin/config/development/cdn make sure you are enabled, and not in testing mode:



Then goto admin/config/development/cdn/other, expand all of the sections and make sure you aren't excluding actual pages.
