Moodle networking is not enabled

You must enable Moodle Networking in Moodle Admin->Networking->Settings

You need to add your site IP to Moodle XML-RPC trusted hosts list

You must add your site IP to the Moodle trusted XML-RPC hosts list, in Moodle Admin->Networking->XML-RPC Hosts

Something is wrong with Joomdle Web Services setup

Something went wrong setting up Joomdle web services in Moodle. Try visiting Notifications page in Moodle Admin->Notifications.

If you get database errors with duplicate keys, try starting over by removing the offending rows/table. Execute these queries in your Moodle database:

  • delete from mdl_config_plugins where plugin like '%joomdle%';
  • delete from mdl_mnet_host2service where hostid=0 and serviceid=4;
  • drop table mdl_joomdle_dummytable

An then, visit Notifications page again.

Moodle Network authentication is not enabled in Moodle

You must enable the Moodle Network auth plugin in Moodle Admin->Users->Authentication->Manage Authentication.

Joomla URL is not configured in Joomdle auth plugin in Moodle

You need to enter Joomla URL in Joomdle auth plugin configuration, in Moodle Admin->Users->Authentication->Joomdle

Joomla URL seems to be misconfigured in Joomdle auth plugin in Moodle

  • Re-check your Joomla URL in Joomdle auth plugin configuration, in Joomdle auth plugin in Moodle.
  • Make sure you include http://
  • Check Joomla multi-language configuration and enter appropiate parameters in Moodle side if necessary
  • Check any mod_security rules that may deny XMLRPC traffic
  • Disable any Joomla security extensions you may have installed

You may also want to visit: http::/yoursite.com/index.php?option=com_joomdle&task=ws.server&format=xmlrpc


If everything is working fine, you should see something like:

faultString parse error. not well formed. error occurred at line 1, column 1, byte index 0 faultCode -32700 


If you get a different message or a blank page, there is some problem with your server configuration.

Received empty response from Moodle

Usually this caused by a misconfigured Moodle URL in Joomdle component. Double check that it is correct and that it includes http:// in front. If you are sure everything is correct, consider that it may be a connection issue (firewall, etc).

Source IP not allowed

This means your server is using a non-public IP address for Joomla-Moodle connections. You will need to enter the displayed IP address in the "Server address" config option, which can be found:

  • In Joomla 1.5, in Joomdle XMLRPC plugin configuration
  • In Joomla 1.6, in Joomdle general config

E_DEPRECATED errors are enabled in your PHP configuration

You have E_DEPRECATED errors enabled in your PHP configuration. You need to disable them for Joomla web services to work.

Look into your php.ini file and look for the 'error_reporting' directive. If you are on a hosted server you may need to contact your hosting company to modify your PHP configuration.

For example, my local configuration is: error_reporting = E_ALL & ~E_DEPRECATED
