Moodle 2.7+ upgrade issue

Hi,

I'm getting an error after upgrading Moodle from 2.6+ to 2.7+.

The upgrade process completes without problems, but I then get the following error when trying to access the site:

XML-RPC Error (17038686): error/parametercannotbevalueoptional | ERRORCODE: parametercannotbevalueoptional

I've upgraded the Moodle from 2.6.2 to 2.6.3 and didn't have any issues. Upgrading to 2.7+ from 2.6.2 (and 2.6.3) causes the error.

Any ideas on what could be causing the problem and how to fix it?

Moodle 2.6+
Joomla 3.3.0
Joomdle R0.95

Thanks for any help.

Cheers,
Paul.

Hi Paul, when do you get this error?

Access the main Joomla homepage? All Joomla pages? Only moodle course pages? When logging in?

Do you get his error message when SSO is off?

I note other posts in this forum suggest that Moodle 2.7 is OK although I have not tried it myself yet.

Also note there is a very similar post here

Thanks for the reply Chris.

I get the error when logging into Joomla with SSO on (I haven't tried with SSO off). I also get the error when viewing certain sections of the Joomdle control panel in Joomla (Users, Mappings), whenever XML-RPC kicks in.

Prior to attempting to log in, Moodle and Joomla seem to function normally (although I still get the error in the Joomdle control panel).

I've seen other posts referring to Moodle 2.7+ and Joomdle working, but only from a fresh install, not an upgrade.

Did you cjeck the post Chris linked to? Maybe you added the moodle functions to the service too...
There are no optional params in joomdle web services, so the message is weird.

Or maybe it is that you already had all functions there, but the moodle upgrade introduces code that now shows the error.
I would try re-creating the service in Moodle, adding only joomdle functions.
