WordPress MU

Hi everyone.
XMLRPC publishing on my main WP MU blog is working, but the subdomain isn't... I think i set it up correctly as I can contact xmlrpc.php via browser (which returns "XML-RPC server accepts POST requests only"), but when i try to post, i get this error

<methodResponse>
<fault>
<value>
<struct><member><name>faultCode</name>
<value><int>5</int></value>
</member>
<member>
<name>faultString</name>
<value><string>Didn&apos;t receive 200 OK from remote server. (HTTP/1.1 302 Moved Temporarily)</string></value>
</member>
</struct>
</value>
</fault>
</methodResponse>

To clarify, i am using
- sub-blog on subdirectory (shared host)
- mapped domain plugin
- XMLRPC client is something I wrote and has been proven (been using it past 7 months on my other WP blogs)
- XMLRPC on MAIN blog is working correctly

The 302 error is probably coming from the mapped domains plugin. Don;t have an answer on that but I did want to point out that we just covered this elsewhere in case you want to fix that to a 301 like it should be.

Not sure which plugin (There's a bunch.) you;re using but the cause is probably the same.

Hey tdjcbe...
Not sure if the updates from that forum thread were included, but I downloaded the domain mapping plugin a couple of days ago.

I tried changing line 453 from

header( "Location: {$url}{$_SERVER[ 'REQUEST_URI' ]}", true, $redirect );

to

header( "Location: {$url}{$_SERVER[ 'REQUEST_URI' ]}", true, 301);

still i get the same 302 error

FYI: Under Site Admin => Domain Mapping => Permanent redirect, i have the box checked... so the logic above should be 301 redirect.

I tested on a FRESH copy of MU (on subdir, not subdomain)
1) w/o domain mapping plugin => XML RPC works fine
2) w/domain mapping plugin => XML RPC breaks (302)

(and domain mapping plugin is the ONLY active plugin)

Anyone have any thoughts?

Try the dev version of Donncha's plugin:
http://plugins.trac.wordpress.org/browser/wordpress-mu-domain-mapping/trunk?rev=235858

hey andrea
i tried the new one... no luck. same error. ;/

On side note: weird thing is.. i tried publishing via:

http://topblog.com/subblog/xmlrpc.php

The XMLRPC client is returning "successful" return code but i don't see any changes to the sub-blog.. but instead on the main blog. I'm assuming this has something to do with the domain mapping plugin.
