I got this in the event viewer when I enabled suslogging.
The description for Event ID ( 2000 ) in Source ( php ) cannot be found.
The local computer may not have the necessary registry information or
message DLL files to display messages from a remote computer. The
following information is part of the event: php[144], PHP Notice:
Undefined index: HTTP_REFERER in C:\siupchat\statusimage.php on line 52.
I can't grok this easily since it looks like it's coming from a strange
OS, but if I were you, I would begin by looking at line 52.

P.S. Please reply to the list.

Why do you think it works on the local site? Is it access to
MySQL? Seems weird since the provcessing should still be server
side on the MySQL stuff.
I will see what I can find in the log.

Since this is open source code ('phpOnline') available at
http://www.dayanahost.com/phponline.cfm
<http://www.dayanahost.com/phponline.cfm>
I guess it's safe to post an excerpt here:
...
[a number of mysql statements without error checking or other exits]
...
[concluding with:]
header ("Content-type: image/jpeg");
if($LastAdmLoginTime==0 || $LastAdmLoginTime<($TTime-120))
{
echo implode('', file('pathtooffline.jpg'));
$OnlineStatus = 0;
}
else
{
echo implode('', file('pathtoonline.jpg '));
}
Since both of these images are present (i.e. can be accessed
directly)
and since there isn't any exit prior to the execution of the above
statement, I conclude that the program must be erring out before
it gets
here.
Check your php error log first. If you don't find anything there
then
edit the program to add error checking for all the sql commands.
You might also find help at the phpOnline forums:
http://www.dayanahost.com/forum2/index.php?act=SF&f=11&;
<http://www.dayanahost.com/forum2/index.php?act=SF&f=11&;>
If you can't find the problem, since the program is short, you could
post it to the list.
