After developing code etc for our website (Windows 7 OS) , a fresh and clean build is done on a QA machine (Server 2008) and the website on that server undergoes formal testing. One page has a grid, and on both sites everything works fine, except that when displayed from the QA server the headers of the grid are blank. This occurs on both IE and Chrome, so it doesn't appear to be a browser issue. I created a test page with no code behind to demonstrate the problem.
Code: C#

I viewed the source code in each case (QA web server vs. local web server) and the only differences - other than resource references appear to be in the 'eo_culture' settings; the local machine specifies en-CA whereas the QA server specifies 'en-US'. This despite ensuring both the QA server and my machine have the same location (USA) and formats (English(USA). But I find it hard to believe that culture settings would cause this.
I can also send the source files in each case if this would help.
