Have you tried on different computers / browsers?
Just got it working. Or seems to be. Been stable for a bit now and the admin page is back.
Had to replace the URL of the site, with localhost:localport
I've got a fresh install of NodeBB 1.13.2.
Resource will be used for some kind of "staff <-> consumers" communication.
Is there any way to permit registration (with admin approvals) for consumers and LDAP login (for staff) at the same time?
