I use form2mail.php (http://www.web4future.com/easiest-form2mail.htm) for many of my client's simple "contact us" forms. These sites are hosted w/ A Small Orange, which supports PHP, so everything works fine... most of the time. For example, I've got a contact form that works for me and it works for 90% of my website visitors... and then someone will tell me they get an "illegal execution" error when trying to submit the form. I am confused as to why it would work for some people and not others?!? Any ideas?
