Re: Server Application error
is it any error number that is displaying like 501 or some other
First check out any errors in code behind file,then try to restart your iis.
after restarting try install and replace asp.net scripts by using commands like
to install --- aspnet_regiis.exe /i
then register using --- aspnet_regiis.exe /r
