Alrighty. I've scoured the board and looked through the codex, and I can't find a solution to this problem.
When I try to switch themes via the theme switcher plugin, I get a page that says,
The document has moved here."
"here" is a link to my blog with the theme I just selected showing.
The list of 2.0-compatible plugins says that Theme Switcher disables the "Current theme option" admin link; is this what is happening to me? How do I go about fixing this?
