Ok well it looked like the Development Edition was udated quite a bit in the last 2 months. As such certain themes are throwing a lot of errors. As such I've made them unusable. I'll get them fixed up in the next day or so. Hopefully if you don't change your theme setting it'll revert back once I get it updated and make it usable.
Sorry all, didn't realize the extent in which the themes would be affected.
