Mark, what's the value of your servers "max_input_vars" setting?
It's possible, with a lot of forums, that your reaching this setting and that's why things are zero'ing out. Try inserting "php_value max_input_vars 5000" into a .htaccess file under your UBB.threads install and check your phpinfo output to see if your host allows you to offset, and if so try to recreate this bug.
I have an entry on the Wiki for this:
Issues with the PHP 'max_input_vars' SettingIt was 1,000 but updated it to 5,000 as you say.
Mark,
Work through with Gizmo, since the problem you're referring to is within your server settings.
Expanding on what Gizmo mentioned above, the input vars should be no less than: "total number of forums you have" x "number of permissions on that page" + "the other group_forumperms.php page strings" (IIRC, that number is 4)
ie; if you have 104 forums, multiply that by 26 and then add 4.
Your vars setting should be
at least 2708.
Setting it to 5000 should resolve your issue.
And you should probably also clear your browser cache, just to be safe

There the ones I know had a value and have changed to zero.
Others permissions have kept there settings view ad island and a nother one or two.
But mainly in this group its 1 members forum so alot of the permissions were zero to start with.
Hope that helps.
