We have had some issues with a blank page appearing, when the page should be served. The reason is that when I go to https://site/ui this is the same as https://site/uitleg-over-vanalles-en-nog-wat
It seems that the UiFeature plugin takes over every url that starts with ‘ui’, regardless of anything that follows.
Disabling the UiFeature with
Plugins.RemoveAll(x => x is UiFeature);
Shows the normal page.
