When trying to access a site on a mobile device. I am getting Object Reference not set to an instance of an object. What in particular would cause this problem. Could I have accidentally removed an item or hidden a control in the new masterpage? This is for a SharePoint Foundation site.
I did some further testing and have determined that if I create a new sub site it works fine. If I change the root site back to the default master page I get the same error.
Interestingly enough I did this search "_layouts/mobile/mblwiki.aspx error" and got back a lot of sites with the same issue. Talk about an easy way to find internet sites built on SharePoint that have been customized.
