I had that issue as well. Here's the fix.
If you're using the public version, please refer to this post:

If you want the admin version, you have to do a little editing to .sp in the post linked above.
I change:
PHP Code:
RegConsoleCmd("sm_votemute", Command_Votemute, "sm_votemute <player> ")
RegConsoleCmd("sm_votesilence", Command_Votesilence, "sm_votesilence <player> ")
RegConsoleCmd("sm_votegag", Command_Votegag, "sm_votegag <player> ") )
to
PHP Code:
RegAdminCmd("sm_votemute", Command_Votemute, ADMFLAG_VOTE, "sm_votemute <player> ")
RegAdminCmd("sm_votesilence", Command_Votesilence, ADMFLAG_VOTE, "sm_votesilence <player> ")
RegAdminCmd("sm_votegag", Command_Votegag, ADMFLAG_VOTE, "sm_votegag <player> ")
and recompiled.
Hope this helps you or anyone else with this issue!
