Hi, Dinesh.
Per our email conversation, I found and fixed the problem. It occurs when using the UAM (User Access Manager) plugin. What happens is that UAM installs a .htaccess file in the uploads folder and prevents Use Any Font from retrieving the font when I changed the permalinds to anything but the default!
Also, if anyone is using Mac OS X Server, and you are changing permalinks, you need to make sure that you have this in the Advanced Settings in the OS X Server App, or Permalinks won’t work.
Hope this helps!
Ron
