Unable to Create New Events

We've updated Joomla and pHP recently. Everything appears to work fine except I just tried to create a new event and when I save it results in an error. I can bring up existing (archived events) and modify / save them with no issues! Any ideas of wha the cause might be? Here is the error:

An error has occurred.
