PS that was for adammenkes first problem

The problem is a subquery is being used but not aliased. It is when the variable @query is being defined

To fix it change to:

set @query = '

DECLARE @cols NVARCHAR(max)

SELECT...

I also got a 404 from my Win Mobile 6.5 (HTC HD2) phone, and also "An error occurred" when just trying the /mobile page.

It let me log in though
