"Invalid Forum permissions specified"

[flashgordon]

I wanted to sort-of revert the permissions of the Not Registered Usergroup to the default of the parent forum.

I had made changes to the permissions of this forum.
So I clicked "Use Usergroup Default Permissions (Note: this will delete any previous custom permissions set)" at the top of the permissions settings for this forum and submitted the changes.
Now, when I want to open the permissions for that forum again, I get the error message

"Invalid Forum permissions specified"

What do I do? Please help.

Hmm, okay. So the problem solved itself.
I can access the permissions of this forum now.

Maybe it was a problem with my browser's cache...
