500 error after adding whitespace in a template???

Ok, Nop does not make it easy for noobs at all.

The problem is, we are trying to theme a site over at http://nop.kro.ie/ and I have just edited ThreeColumn.Master.aspx and it now throws a 500 internal server error. All I did was add a space?

Is Nop really buggy??

you may use ;nbsp to replace the whitespace.

Thanks, but what is the reason for the 500 after such a simple "edit" ?
