Moving request priority yields "internal server error"

Whenever I re-arrange my request queue, I get an "Internal server error." (red words hovering over favorite list). Upon song the next song being played, my changes to my request queue are reverted.

Same here. I'm trying to match tracks in the queue list and I've got "Internal server error" too
