There are two buttons in the media library. The buttons themselves don’t link to anything. Instead, the buttons are put on a page or post and a link is inserted for each one. The link is HUGE. https://www.eservicepayments.com/cgi-bin/Vanco_ver3.vps?appver3=tYgT1GfNxRUldiimjHMvOSsPy3TkB2e6q81QoJa0avDI7vfWxf7GD2jGKof53LUH2evTpo0mld6BrVzd2nG0pwapIzYIua1_i-72cgFBccc=&ver=3
This button has the link to eserve in it.
