Hi

We're trying to run the edit/admin UI on a different port and have been following the guide here:
http://world.episerver.com/documentation/Items/Developers-Guide/Episerver-CMS/9/Security/Securing-edit-and-admin-user-interfaces/

We're not interested in changing the UI "path" from the default (/EPiServer/CMS/), we just want to run it on a different port.

The guide says that to use a different port, we need to update the "uiUrl" property in our Web.config to include the full path and port which we've done, so now our uiUrl value is:
https://episerver.mydomain.com:8888/EPiServer/CMS/

The guide then says to change a bunch of other paths in the config, for example from ~/EPiServer to ~/newuipath, but as we haven't changed the "path" part, we've left them all at their defaults so the only value we changed was the "uiUrl".
We can now access the CMS on port 8888 but as soon as we hit the edit or admin links, we get the "Incorrect link" error:
Incorrect link
The link you gave does not work, either because the page it points to has been deleted or moved.
If you clicked on a link, please inform the site’s webmaster that the link is faulty.

I've tried so many combinations of things in the Web.config based on what the guide says and can't get this to work.
Any help would be greatly appreciated!

Thanks!

Anton
