Re: Unable To Edit Group Permissions With Too Many Forums.
-----------------------------------
This is really strange... In any case it is not suitable having so many subforums, because this setup will require an high amount of  memory consumption (even caching files will be big). You will experience even high generation time with all these forums.

In your case the error could be related even to "OUT OF MEMORY" error... try to raise memory limit.

If you can provide a backup of your setup I may try as well to replicate the error.
