public OnPlayerCommandText(playerid, cmdtext[])
{
	if(!strcmp(cmdtext,"/info",true))    //you forgot the !strcmp, and use boulean true.
	{
		SendClientMessage(playerid, WHITE, " World Wide RolePlay");
	}
	return 0;
}
}

Just do it this way, btw if you use isplayerconnected, you have to use a boulean too, but you are a beginner, so I would start with this.
