Joomla URL seems to be misconfigured in Joomdle auth plugin

I'm currently using Joomla 2.5 and Moodle 2.2.. Been installing and configuring moodle, joomla and joomdle for a few days but still receiving an error during system check in joomdle. At the joomdle system check, it displays red at the Joomdle Web Services giving me the error: "Joomla URL seems to be misconfigured in Joomdle auth plugin in Moodle"

Using the suggestion here , I tried to solve it but fail.
I checked my xmlrpc and it seems fine, giving me the error,
"XML-RPC Error (1): Access Denied::1"

I did a clean install on it, so currently there's no Joomla security extensions on it.
I disabled my language filter in joomla and set the English(en) as my default language for moodle .

The only thing i didn't try is checking the mod_security rules. Not sure how it works...



Any help would be appreciate.
Thanks in advance.

You said:
> I disabled my language filter in joomla

But you have configured Moodle side to use "en". You should disable that.
