Add Favorite Adopt to sidebar?

Aquapyrofan and I are working together on this, so I've got a couple questions, since I'm having trouble getting this working as well. We've tried to set it exactly as you said, but it's still not working. As such, I was wondering whether the alchemy or item drop mods, or the fact that it was not installed at the domain's root, would be issues?

EDIT: tested on a clean install under WAMP, it still doesn't work
