Omeka/Wiki issue

I have installed Omeka 2.3/scripto and have it all working (as in I can upload images and then edit/save edits). I have noticed two issues though:

1/ On the transcribing pages if you click wiki inbetween edit and history it goes to localhost/mediawiki/. This obviously work if Im remoted to the machine but on any other machines its not loading, how do I change that reference to go to domain/media wiki instead?

2/ In the omeka admin page when looking at an item, if I press import page it changes to importing but then back to import again. Nothing seems to happen?

Help is much appreciated.
