Cannot configure certain features

Hello,

I'm having an issue with trying to configure email notifications. Actually it's 2 issues.

1 - I cannot successfully get to the Server Settings section under Admin -> Product Settings. Clicking Server Settings will load some of the page, but I cannot see anything under the Mail Settings tab. I can also not click SMS Settings or Proxy Settings to load those tabs. Both the Connection and Windows Service links under Product Settings seem to work fine; it's just Server Settings where I have this issue. I have tried this in IE, Firefox, and Chrome, and they all show this same behavior.

2 - Under Configuration -> Password Expiry Notification, clicking the Add New Notification button does nothing. I can click it all day long and absolutely nothing happens. I don't know if this is related to the issue above, but it is a problem I need fixed.

Hopefully someone can help correct these issues.

Thanks,
Sean
