Selected 404 Page ignored; shows default Umbraco 404

Hullo ^^

Quick question that may just be the answer to my problems:

Does the 404 settings > Page Select just not work at all in trial mode on localhost, but still break custom 404s?

Or am I missing some setup? I’ve glanced through the documentation pdf but didn’t spot anything (though I could be blind)


I’ve been trying to get the 404 settings to work with no luck. Previous to installation of this package I had a successful setup of a custom 404 page using the default Umbraco Error404Collection setting in appsettings.json.

After install I can’t get anything to work.

If the SEO Domain settings > 404 settings is blank, my Error404Collection appsettings is ignored. Default Umbraco page 404 shows.

If the SEO Domain settings > 404 settings has a selected page, it changes nothing; default Umbraco page 404 shows.

I tried removing the appsettings entry but it changed nothing.
Otherwise, using latest SEO Checker (v13.1.0) & latest Umbraco (v13.1.0).
