Cannot create account

I have cpanel/whm setup on a VPS with 60GB+ diskspace and 2GB ram. Today, I am unable to create any accounts, not even on root.

When I go to account creation, the package area says that it cannot use due to limits. I'm not even close to limits, and I've looked everywhere for an option that limits how many accounts can be created server wide, and I can't find it... I thought maybe reseller center, but there is no option to edit root, only resellers.

Let me know if you have any ideas on what could be going on, what I should check, or what I should do to get it fixed. Your help is appreciated.

Thank you.

 

I should have finished creating the account before I posted, it does create the account, but I don't see a reason why it says "cannot use due to limits."
