I seem to have butter fingers or a very close relationship with Murphy going on lately. I tried adding Donncha's Domain Mapping plugin to my MU install, and was *this* close to moving my wife's blog over when...
...it broke a lot of the plugins being used on the domain mapped blog. I'm assuming this is more a problem with the plugin itself than the domain mapping, but it pales in comparison with my next problem anyways.
The front page of the newly mapped blog works just fine. None of its pages do however. Everything I click on returns an internal 404 error, and not a theme based 404 so... I'm wondering where I went wrong yet again.
