Error Message In Control Panel

Hello, I am having trouble displaying my Admin main page. When I go to the main page of my Admin CP, it gives me this error.



Code:

I'm receiving the exact same error. I assume it's something to do with PHP 5 as my server has just been upgraded. However, I'm not a programmer and have no idea how to fix this.
