mutags sub-domain problem

Hello:

I have installed the mutags latest version. It pulls all the tags and even displays them in a page result. But I can only click on the local (main) blog search results. Posts from other sites redirect to the same page.

Take a look at: http://meradera.com/

towards the bottom right hand side is the tag cloud. Click on gizzy or http://meradera.com/tag/gizzy/

the first result is a post within the main site. It links fine. The second post is at http://gizzy.meradera.com/ and it does not link at all.

please help. I signed up here just to solve this problem.
