Error Viewing Post after 1.6 to 2.0 Upgrade

Jan 3, 2011 at 6:34 PM

Upgraded to 2.0 from 1.6 and everything works fine on my local box.  After uploading to public server I get the following error when trying to view post. 

[NullReferenceException: Object reference not set to an instance of an object.]
   App_Code.Controls.SimpleCaptchaControl.OnInit(EventArgs e) +35
   System.Web.UI.Control.InitRecursive(Control namingContainer) +333
   System.Web.UI.Control.InitRecursive(Control namingContainer) +210
   System.Web.UI.Control.InitRecursive(Control namingContainer) +210
   System.Web.UI.Control.InitRecursive(Control namingContainer) +210

   System.Web.UI.Control.InitRecursive(Control namingContainer) +210
   System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +378

It's only when I view post via .../post/2010/11/28/name.aspx .  The main page works, updating post works,etc...  Seems like everything else is working, But I can't view individual post...

Don't have any 3rd party controls/addon's etc...   Any ideas?
