My box is supposedly Linux - it's go daddy which I know is notoriously sucky. But dig this. I get 404 errors when I send a normal ping to the blog from elsewhere. I read on this board that hacking in td_id would help... but -->

If I hack the: ?td_id= thing in, then I get the following activity log error:

Ping 'http://www.sustainabilitydictionary.com/cgi/mt/mt-tb.cgi?tb_id=5' failed: Need a TrackBack ID (tb_id).

Likewise, this is no good:
http://www.sustainabilitydictionary.com/cgi/mt/mt-tb.cgi/5

But this,
http://www.sustainabilitydictionary.com/cg...-tb.cgi?td_id=5


Gives a peculiar XML error:

This XML file does not appear to have any style information associated with it. The document tree is shown below.

Clues?

Did you rename your trackback script and possibly not update mt-config.cgi? It looks like mt-tb.cgi isn't on your server.

Nah... it's here: http://www.sustainabilitydictionary.com/cgi/mt/mt-tb.cgi

Didn't change anything... yet

Weird. I got a 404 when I tried to ping you.

Is it possible that you're on a Windows box? (The answer is no - you're definitely on Linux because I peeked at you mt-check.cgi.) It still might be a similar problem though.
404 on Trackbacks

Right - it's linux. When I follow these instructions (link here) then I no longer get a 404 error, but I do get the weird XML error quoted above... it's maddening.

Could I have you do an experiment? Could you edit lib/MT/App/Trackback.pm (make a backup first) and change line 152 from:
$app->translate("Need a TrackBack ID (tb_id)."))

to:
$app->translate("Need a TrackBack ID ($tb_id, $pass)."))

And see what your error says when you ping
http://www.sustainabilitydictionary.com/cg...-tb.cgi?tb_id=5

hmmm ok... did it. Seems to do nothing:

I did a post on another blog referring to both:

http://www.sustainabilitydictionary.com/cg...b.cgi?tb_id=214
http://www.sustainabilitydictionary.com/cgi/mt/mt-tb.cgi/214

The error log says:

Well, it's right. It's definitely not seeing your tb_id even though it's right there. Hopefully someone else who has spent more time in the code will read this thread and help us.

bummeriffic... thanks so much for looking at it!

Yeah, hope there's a way... trackbacks are a key part of this projcet. Ah well... i'll keep tinkering.

Here is how i solved it. In lib/App/Trackback.pm there is a function called _get_params. It is set up to not search the query string for the params so I changed it from this:

sub _get_params {
my $app = shift;
my($tb_id, $pass);
if ($tb_id = $app->param('tb_id')) {
$pass = $app->param('pass');
} else {
if (my $pi = $app->path_info) {
$pi =~ s!^/!!;
$pi =~ s!^\D*!!;
($tb_id, $pass) = split /\//, $pi;
}
}
($tb_id, $pass);
}


to this:


sub _get_params {
my $app = shift;
my($tb_id, $pass);
if ($tb_id = $app->param('tb_id')) {
$pass = $app->param('pass');
} else {
if ($tb_id = $app->query->param('tb_id')) {
$pass = $app->query->param('pass');
} else {
if (my $pi = $app->path_info) {
$pi =~ s!^/!!;
$pi =~ s!^\D*!!;
($tb_id, $pass) = split /\//, $pi;
}
}
}
($tb_id, $pass);
}


Seems to have worked fine. I don't know if you actually need the code

if ($tb_id = $app->param('tb_id')) {
$pass = $app->param('pass');
}

but I left it in anyway just in case.
