Having Issues with Social Media Plug Ins

My website: www.grabyajimmie.com I am having issues with the Facebook plug-ins. I keep getting the error message: 503 Service Unavailable: The server is temporarily unable to service your request due to maintenance downtown or capacity problems. Please try again later. I talked to GoDaddy about the issue and they're saying it may be something with the theme. I have changed different plug ins and Im still getting that error. Please advise. Thank you.
