I'm not sure how to get to the web server logs, and I do not have any error handling in there. The only javascript is to highlite and unhighlite the button onmouseover and onmouseout. The weird thing is that it processes everything and puts the information into a database even for those people that get the error. I get something like this when I try to delete mail on my yahoo mail account, but only when I use firefox, my site works for me with firefox and IE though, but when I use IE for yahoo mail it works fine. I get a page Cannot be displayed with this error when using FireFox for yahoo mail.
"HTTP 502 Proxy Error - Access is denied. (5)
Internet Security and Acceleration Server"
I am currently trying to find if this is the same error that they get.
