MyBB Community Forums

I have a new forum that uses MyBB 1.8 and I have a few plugins installed.
I noticed that there might be a bug in the ACP.

ACP->Forums & Posts->Forum Management->(Click any forum.)->Permissions Tab

Should be in a page looking like this:

When I click "Set Custom Permissions" and then click the Cancel button, a blank page appears with nothing but this:



I have disabled all of my plugins and it still happens.

Is this happening to anyone else? How can this be fixed?  

run file verification tool available at tools & maintenance section of admin panel.
focus is on missing / changed files from admin folder. ignore images & install folder.
if you see any missing / changed files then replace them from MyBB 1.8 files pack & check

I tried it and it only showed a few changed images and missing install files.

Yep, I can also reproduce it - it's a bug so moved to a proper forum.

I can confirm

If you guys confirm it, I'll push it.
