I agree with Wicked. If the amxmodmenu command is not working, you should find out why because the source of this could be causing other things to not work as well. Post the full output (copy/paste) of the following command in the server (e.g. via HLSW):
meta version
meta list
amxx version
amxx list
Regarding your plugin issues, you'll need to read the errors and try and fix them. Most errors explain what is wrong and can easily be fixed.

P.S. The bind command has been blocked by Valve when being sent by the server. Therefore, it will not work. Also, changing client settings is not supported here and is known as "slow hacking".
