Some users may have permissions to edit multiple sites. If they login on a site they don't have permissions on, the "Pages" link to the change_list view in appindex is not linked (although there would be pages on other sites that the user could edit). Once on the change_list view with a site selected that the user has permission on (eg "/admin/cms/page/?site__exact=6") all is ok again and the dropdown appears with all sites the user can edit.
working on a fix
it should be finished by now :-D
probably fixed / not relevant anymore. I'll check. really. most likely.
where is this fix? ;)
let me check... hmm. Maybe up there. No. Down here? Nope.
No fix to be found :-(
@stefanfoulis is this still relevant?
