The Restrict Ambient Voice module appears to be broken.
I get an error (did not return an array) no matter what classnames I put into it. Someone else has also confirmed they are having the same error.
This is what I have in the module that is causing an error.
["vn_b_men_sog_14", "vn_b_men_sog_06", "vn_b_men_sog_10", "vn_b_men_sog_22"]
