We are programming our OpenCart software to hold the affiliate tracking code in the address bar (i.e. &tracking=4f8d9e221c497) so that affiliates can share products to social networking sites using AddThis. But whenever an AddThis button is used it strips off the tracking code &tracking=4f8d9e221c497 and replaces it with other random tracking info like #.T42oHxgFtrs.twitter. How can we fix this as we would love to use AddThis on our site.
