We have many customers complaining that they can't complete an online order because the submit button that we describe in our instructions isn't appearing on the web page. When we try this, it works perfectly well. The only clue we have is that some of them reported having anti-virus and/for firewall software installed.
I am not aware of any anti-virus/firewall software that would be set to specifically block online forms or submit buttons, however. Is anyone familiar with this and could recommend a workaround?
Another possibility as to the cause is that our initial online form submits from our non-secure site to a secure site on a different domain (but that can't be changed due to our relationship with the secure site...the initial form has to reside on our site and then it has to submit to the secure site). Could the fact that they are on different domains cause this "hidden submit button" issue?
