Hello the plugin didn't work at all! add all the files in their corresponding folders and the main crx_chatmanager.sma file compiles it and install it in plugin then copy the name of the plugin and paste it into plugins.ini, the second crx_chatmanager_toggle plugin does not install it since it is not necessary as you I mention
So because the error has been generated, the plugin does not load well, in the console when I put amx_plugins it tells me bad load.
