I have consulted some programmers and sought help from my server provider(webhost4life). But all of us do not know the reason.Any Solution?Many Thanks!!!
Thanks for your attention!yes, there was not any error message after I clicked the Add button.but, there was not any other reaction too.I have checked the Event Log and it suggested that it has Add a text/html to the panel, but I can't see it on the web! why happened that?
