( t's probably being called in src/page/page/updatePermissionsCollectionID() )

Seems to have to do with the permissions system.
Are you logged in as admin (superuser) ?
Did you enable advanced permissions ?
Did you change any permissions (especially for pages) ?

I am logged in with Admin

I do not know what the advanced permissions are and therefore didn't change any permissions

I created a new page type, I must have screwed up the first time, my second attempt works.

good to hear !

good luck with your project

Yeah, there seems to be a peculiar bug that crops up with Custom Page Types sometimes.

This thread also discusses it:
