FreeRadius2 fails to start after upgrading to 2.2.4

[pfSenseRocks]

Any help rectifying this is appreciated. I have tried reinstalling the package.

Here's the tail of the radius.log.

There seems to be an issue with your server certificate. Go to 'EAP'  tab under FreeRADIUS config and make sure 'SSL Server Certificate' field is populated. Then save the page and try to start the server again.
