Browser key not working

Hi. Thank you for this free plug in and I am anxious to use it. However i cannot figure out the api key. I have the billing all set up properly. The server key is working. Browser key is returning the error that I checked in the Javascript console and it is the referrernotallowed error…this site needs to be authorized….I put in the main site link by referrers and also the longer url it gave me in the error there as well and still nothing. Please advise. Thank you!
