#1 = send a mail only when the page contains your DOMAIN NAME
#2 = even if a disconnected connection occurs with me, it may be a site of friendship.
$ Reportlevel = 2; // This is the safest

$ Emailaddress = "webmaster@oso.com.cn"; // Set the mailbox for receiving error messages


Function PRint_details ()
{
# Request access to the global variables we need
Global $ fontface, $ fontsize, $ docroot, $ REQUEST_URI, $ reportlevel;
