JobRoller - HTTP Error 500 (Internal Server Error) - Install & Setup

[hazman]

Hi,

I have having this error below, upon activating the theme. I am using this theme at one of my sub-site(multi-site). I also try to install it at the single installation, and getting the same server error and in this single installation, there is no plugin activated. I am running on the latest wordpress platform.

Server error
The website encountered an error while retrieving http://www.justworldorder.com/jobs/w...ns-general.php. It may be down for maintenance or configured incorrectly.

Here are some suggestions:
Reload this webpage later.
HTTP Error 500 (Internal Server Error): An unexpected condition was encountered while the server was attempting to fulfill the request.

Please help me.
