I'm having a trouble reproducing an issue a user is having in IE, but something that always bugged me is how can I see the error message from classic ASP page in IE for example on a dev server.
In IE all I see is for example:
This page contains programming error
And that's it.
Note: since this is server side, it applies to all browsers.
I remember this one!
You need to go into ie settings > advanced > uncheck "show friendly http errors"
Gabs
Is the problem just in IE? anyway i found this link that might be helpfull:
