This plugin has been blocked by a subsequent Valve srcds update.
This isn't a mms plugin, but I'm posting info here in case you're running a plugin that uses client commands and is no longer working.
I just released a plugin to set cl_restrict_server_commands to 0 on clients who have it set to 1. The plugin checks the first time a player spawns onto a team (including on map changes) and if cl_restrict_server_commands is set to 1, the plugin will change it to 0.
I've taken Roman Hatsiev's idea and added a notice to the players that the server requires running client commands. The player can then either click OK to play on that server or disconnect if they're not comfortable playing on a server that will run client commands.

I'm hoping that since a warning is provided, Valve won't block this method in the future.
