Issue: Users can't edit wiki pages

If a page cannot currently be edited by you or any other admin, but you have edited it before, then maybe there are changes waiting for moderation. If there are no wiki moderators assigned at all (including yourself), then I'm not sure if anyone would know about the changes or be able to approve them. You might be able to approve them by visiting the page directly if you have Moderator Permissions > Can moderate wiki content? (a user does not have to be assigned as a wiki moderator to have this permission)

If a page can currently be edited by you but not by any other admin, visit the page and check Options > Protect From Further Changes. Make sure that Collaboration Protection is not turned on. Such a page can only be edited by the page's creator and users with the Moderator Permissions > Can edit wiki content? (a user does not have to be assigned as a wiki moderator to have this permission).

If neither of these explains your situation, please fill out a ticket, providing an admin account that cannot edit and links to 3 pages that can be edited by you but not by the supplied account: https://www.vaultwiki.org/members/?do=tickets

Unfortunately, neither of those explain my situation as far as I can tell. I've submitted a ticket.

This is fixed in the next release.

This occurred when using Admins-Only Protection on an article. If a user was in the Administrators usergroup, but was not defined as an Administrator on the AdminCP's Administrators page, the user would not count as meeting the criteria for bypassing that protection.
