Apache error log shows Undefined variable: username error.

Hello and Greetings,

I have Moodle 3.5 and Joomla 3, have installed Joomlde. The system check shows all OK.
When i go to users section it shows green tick in only one place either moodle account or joomla account. If i click to add to moodle or vice versa it just shows Joomla Account.
upon checking the Apache error log following error is received.
PHP Notice: Undefined variable: username in /home/moodle/moodle/auth/joomdle/auth.php on line 4362
Any help in this regards much appreciated.

Thanks and Regards,
Kunal.

Hi all, problem sorted out with re-installation of Joomdle on both sides.

Thank You.
