If you have a Page Reference field set to choose Repeater items you may have found that when you log in as a user that doesn’t have the
superuser role then the field is blank. This is down to ProcessWire’s permission system.
To fix this, in the Input tab expand the the Selector string panel and create a selector that gets your pages and add
check_access=0 to the end. E.g.
template=repeater_products, sort=title, check_access=0
The field will now work as expected.
