MODx Revolution - Timeout happens every minutes causing logout
===

Setup:
MODX Revolution 2.2.4-pl (traditional)
Hosting: HostGator Shared Linux server

Problem:
After I have logged into the CMS, when I go to make changes to a resource, snippet or any other facet of the site, regardless of how long it took (10 seconds to 10 minutes) I get a screen saying session timed out and have to login again.

I've got 50 installations of MODx on my Dedicated IIS7 Rackspace box that have never given me a problem. 

I only have one Warning which I've never seen before in the Manager Panel:
Configuration warning: register_globals is set to ON in your php.ini configuration file

Any thoughts on why it would be kicking me out almost every time I go to make a change?
Thanks in Advance for any help.
