Purchased License still have the error have no idea what to do

I have tried everything mentioned on the forums  dunno how the problem happened only add a favicon file and cleared the cache : 1 You have manually removed BoonEx footers without paying for the right to. Please, go to BoonEx.com and order the ad free licenses to be able to use your site without BoonEx footers. They will be automatically removed as soon as you register your ad free licenses. Please, put the __boonex_footers__ key back into Dolphin template..
