I believe You are talking about problems You have on dedicated server (when You join there from another PC).

If You still has troubles to get it working - try to use the plugin which is included into All-In-One - amxx_podbotmenu. All You need to control bots is - You just need to invoke the menu from that plugin by the console command:
amx_p
bmenu
I've bolded it because sometimes the people are trying to write amx_pdmenu (instead amx_pbmenu) and of course it cannot work at all.
