404 Monitor redirecting links that are OK to links that are not!

I have been contacted by people stating that some of the links on my site do not load.

The ones using firefox are seeing this: The page isn’t redirecting properly

So I thought that I would check the 404 Monitor as I have been having a lot of fun with this (NOT!)

And sure enough, there are entries for all of the pages that I cannot access on there, but they seem to be trying to reference pages that do not exist, i.e. they are redirecting from a working link to a made up link.

For instance I have a link that goes to the following address:

https://www.md0mdi.im/5cx1500a

This is a valid page, that exists, but for some reason under the 404 monitor there is a perm 301 link been created by the 404 monitor that redirects this page to this address:

http://www.md0mdi.im/myvalvedatabase/5cx1500a

Which is wrong in two ways, the web page link doers not exist, and also its not on a http:// website but a https:// website.

Why does the 404 monitor do this?

I have tried deleting the links, changing them and even switching off 404 but even clearing down the cache on all our systems and rebooting , we still cannot access these pages and if we do they want to redirect to the incorrect links.
