Links in pages and posts to other networked sites are being RE-Written by domain mapping plugin.
Here is how to reproduce this major issue:
Wordpress MU setup with 2 or more sites created with sub-directory.
Site A gets a domain mapped to it.
Site A has a page which links to another Networked site.
(Ie. story.writing.com links to blog.writing.com/blogsite-B)
Site A with the domain story.writing.com will over-write the URL in the link and make it story.writing.com/blogsite-B which doesn't exist and is causing me a world of frustration!!!
This is a major issue for us! Please help fix this.
