PHP Code:
g_iPing = FindSendPropOffs("CPlayerResource", "sm_iPing");
A little extra there. It should be "m_iPing".
PHP Code:
g_iPlayerManager = FindEntityByClassname(MaxClients + 1, g_szPlayerManager);
Shouldn't MaxClients + 1 be -1 instead?
Also, I think this should be ANY? instead of just CSGO. Just by looking at the code, it seems to support multiple mods.
