Something strange is going on here: I created a very simple web app and if I put this line on web.config:
< globalization requestEncoding="utf-8" responseEncoding="utf-8" culture="mt-MT" uiCulture="mt" / >
I get a nice error:
Parser Error Message: The <globalization> tag contains an invalid value for the 'uiCulture' attribute.
At some point in DNN we try to do:
Set(ByVal Value As CultureInfo)
Thread.CurrentThread.CurrentUICulture = PageCulture
Thread.CurrentThread.CurrentCulture = PageCulture
End Set
So maybe this is causing this problem...
