For some reason iis is NOT displaying the custom error pages i made for 404. Instead it just returns a blank page. I have the following configuration. Under action Edit feature request custom error pages is selected. And under the error page there is a row
Status code: 404
Type: Execute url
Entry type: local
Other sites on the same server do not have this problem the only differenct i could find is that their entry type for 404 state inherited instead of local.
Well hope anyone can help
