Joomla cannot connect to Moodle

Just upgraded our Joomdle component to 0.82 (was previously 0.61). Also upgraded Moodle Joomdle integration (Moodle ver 2.2). Now get the following error when I run the System Check:

Moodle cannot connect to Joomla

There's another error that also appears, but it also existed before the upgrade. That error is: Received empty response from Moodle.

Looked through the threads in the forum and found a similar issue, and have double checked that the web services and xmlrpc in Moodle are enabled, and that the URL entered in the Joomdle config in Joomla contains "http://".

How can I resolve these errors?

Thanks....

Do u verify if the user has permission to use xml-rpc protocol?!

The user had this permission before the upgrade, but I haven't verified that it still does since the upgrade. Would the upgrade affect the previously defined user permission?

This problem seems related with Joomdle update.

Did you check all the Joomdle files in moodle are updated?

Go to moodle administration / Notifications and check Joomdle is updated.

I'm testing the new Joomla version 2.5.6 and I got the same error.

It's a new install so no previous errors. Only the VPS, located in OVH, could be the problem. The rest is done as usual.

Antonio, could you explain us when this error rise?

Thanks

PS: I attach the errors screenshot

Thanks for all the replies. I did verify that the Joomdle files in moodle updated. I also verified that my joomdleconnector user for the web service has access to xml-rpc protocol. Rechecked System Check in Joomdle configuration in Joomla and still showing the same errors.

Any further help would be greatly appreciated... thanks!

Just to help rule out the Joomla latest update causing Joomdle to not work, I'm currently running a development / test site with Joomdle 0.82, Joomla 2.5.6, Moodle 2.3.1 and no errors - on a VPS.

Are you using any sub domains in your configuration settings of Joomla/Joomdle, Moodle/Joomdle, or Moodle config php file? I was getting errors when using sub domains instead of the http://www... settings.

I verified that the Moodle auth token was correct. Your comment about subdomains got me thinking tho - I checked the config.php that I had set up for Moodle and it was pointing to our alias domain name (e.g. myaliasdomain.com ) for the $CFG->wwwroot setting. When I checked the configuration in Joomla/Joomdle and in Moodle via Plugins->Authentication Joomla URL name - they were both pointing to our actual domain name (e.g. www.mydomain.com ). I modified both of the latter settings to point to the alias domain name and reran the System Check and it worked! All green check marks is a thing of beauty! :cheer:

Thank you SO much for all the help - it is greatly appreciated!!

Great!! It works!!

I never had this issue before. Just check in moodle config.php :

$CFG->wwwroot = ' domain.com/moodle ';

it should be the same that moodle URL in Joomla. Without www

Thanks!!

Great. Thanks for your help Ron & Fernando
