Jon FrontPage was always horrible when it was active but, as Bala says, it is no longer being supported by anyone. What exactly is it your site needs it for as it's possible someone could help ease the transition.
I had a similar issue with my forum not working. I checked the error log via cpanel and it turns out that they have changed something on the server so access to my forum was being blocked because it's permissions were set to 777.
Well Matra may be up and running but it's got issues. http://carbonize.co.uk/ you get a 404 and if you try to FTP in you get 421 Home directory not available.
Can login to cpanel but File Manager says there are no files in my home directory.
Well I submitted a ticket and have just spent an hour or two with some tech who got it in to their head that there was no issue because the emails are being received by the Gmail server with no errors :|
I probably shouldn't of used the term blocked but pretty sure I didn't say that in my ticket. Just checked and my ticket clearly states that Gmail is now classing all email from matra as spam.
The subject says it all. Gmail is now classing all email sent from matra server as spam.
So not sure if this is Gmail being overly touchy with their spam filtering of if someone on matra has been compromised.
