Thank you to everyone for your comments and suggestions. If Ecwid is the culprit then it makes sense that a form widget on a "request a quote" or "contact us" page would create the same problem. It seems that although a culprit has been found that there is no solution. Maybe this can be fixed in the next Web Designer version?

Inge, I assume that each visitor has control of their renewal frequency and is not something that I can influence. Correct?
