XML-RPC

Good morning to everyone.
Joomla 2.5
Joomdle 0.8
In system check it gives me status down without specifying any error. If I go under users, course requests or shop the site give me the following error
"XML-RPC Error (0): exception in acces control" my translation for "XML-RPC Error (0): Eccezione nel controllo accesso"
.
Any idea ?
I recheck all the installation step under moodle and joomla and everything seems to be ok.

Sorry I don't quite follow this statement "In system check it gives me status down without specifying any error"

Do you mean that all the checks are green? Is there any red X under system health check? If so, which one and what is the error message.

Sorry. The last voice is red, but with no error. It's just red.

OK much better. You can find the list of potential problems here www.joomdle.com/wiki/System_health_check under Joomdle Web Services

You will need to go through one by one to eliminate those that are working vs those that are not.

Hi. No way. In the attached image you can see what happen. I've done everything three time just to be sure.... I can't find my mistake...

You may have a problem with the token in Moodle.

Don't know how. I've made a new installation of joomla and a new installation of moodle. Done everything as before, and now on the new sites, everything is working. ??? Solved....
Thanks to everyone.
