When attempting to save the settings (admin/settings/site-information) I get a "Page Not Found" error.

The log basically gives this: Details Type page not found Location http://www.../admin/settings/site-information Referrer http://www.../admin/settings/site-information Message 403.shtml Severity warning

This is a multisite setup, and it's on a shared host which recently changed the server to improve performance. My best guess is that mod_security settings changed during the move from one environment to the other, but I'll have to open a ticket with the host. Any other ideas before I go down that path?

Thanks, Brian
