Been at this for several days.  Basically I'm getting a 'page load error' when the Facebook callback with token gets hit.  Yes, i've read a number of Posts which say to set AJAX to false.  So, I do that and the Login works I get my Token, however this causes the web-site to reload but not all the Pages - so I start to get Javascript run time exceptions because certain Javascript functions in other pages which are called in the .Ready function are not found because they're not loaded.

I'm using MVC4/C# Server side.

Any help would be much appreciated. 

Thanks,

Joe
