Hello gms111,
1. Unfortunately we have some backend issues, within the next few days everyone should be able to unsuspend themselves if they were suspended for inactivity as they use to be able to.
2. Most of the errors should be resolved now as the server you're on is pretty well finished most/if not all of its maintenance. Create a new ticket if you have any more issues with it.
3. That's just because the SSL certificate is now self signed, not signed by a company like verisign. It's still secure. Don't worry.
Since your issue is resolved i am going to close this ticket. If you have any more issues please post again.
