Joomla URL seems to be misconfigured in Joomdle auth plugin

Hello,

Here the elements of my installation.

• Joomla 3.2
• Joomdle v 1.0
• Moodle 2.8
• Server: Version 1.8.3 XAMPP with PHP 5.5.6
• Windows 8.1

All elements are very well installed, Joomla, Moodle and Joomdle. But when I do the system check, I always get this message:

Joomla URL seems To Be misconfigured in Joomdle auth plugin in Moodle.

I have done all this:

• Re-check your Joomla URLs in Joomdle auth plugin configuration, in Joomdle auth plugin in Moodle.
• Make sure you include http: //
• Check Joomla multi-language setup and enter appropiate parameters in Moodle side if Necessary
• Check Any That May mod_security rules deny traffic XMLRPC
• Disable Any security Joomla extensions you-have installed May
• Disable Any Joomla SEF extensions May you-have

But nothing changes. I always get this error message.

Is it there an item in my components that would not be compatible?
What else can I do to make this work ?
Thanks for help

Stephane

Usually this is a result of
- the Joomla URL defined in Moodle is incorrect;
- XML-RPC not installed and/or enabled
- SEF issues / incompatibilities

Here are some threads that have similar error messages

Note: When installing locally on Windows 8.1 many applications struggle with either 127.0.0.1 or localhost. In the first link above, I have posted my configuration which is windows 8.1 + XAMPP.
