Change this at the top of the .sma to your server's file:
Code:
new HTTPFILE[] = "http://www.espug.net/users.ini"
Also, amx_addadmin has been removed.
I can maybe write up a PHP script to run with this plugin for amx_addadmin to work but not yet.
You need to be running
this plugin BEFORE admin_http.amxx in the plugins.ini
Also, you will need to compile locally with httpdl.inc
