For some reason when I attempt to change any of the usergroup settings (space, permissions, etc) when I save the information I get a blank page, and nothing ever saves. All other changes in other settings seems to work just fine, but the user group changes don't.
vB 3.6.5
PP 5.6.2 integrated but with separate DB's
Apache 1.3.37
PHP 4.4.7
MySQL 5.0.37
Any idea what might cause this? Let me know if I can provide additional information.
