"Could not retrieve data from URL"

Hi,
I grabbed your plugin from WP Business Directory since I’m using it too : )

BUT, now I am getting the message “Could not retrieve data from URL” in the debugger and I have no idea why. It has been working right along.

Any suggestions would be really helpful!

Thanks!
