galper Posted March 6, 2008 Posted March 6, 2008 Hi, Users recently started having the following error when they purchase something on my website: Your credit card was declined. Please try another card or contact your bank for more info. Invalid Configuration (10550) This transaction cannot be processed. It worked just fine and then suddenly it stopped and now I am getting this error consistently. Please, assist! Thanks, Yevgeniy Quote
