Error link account

Hi!

when I try to link a user to a moodle account from the users list, the server crashes because of a infinite loop. I checked the user.log from eb-logs:

02-14-2017 @ 13:38:16 – Checking if username exists….
02-14-2017 @ 13:38:16 – Checking if username exists….
02-14-2017 @ 13:38:16 – Checking if username exists….
02-14-2017 @ 13:38:16 – Checking if username exists….
02-14-2017 @ 13:38:16 – Checking if username exists….
02-14-2017 @ 13:38:16 – Checking if username exists….
02-14-2017 @ 13:38:16 – Checking if username exists….

It seems that is a problem with this loop in class-eb-manager.php (function createMoodleUser):

// we will check if the username is vailable on moodle before creating a user
while (!$this->isMoodleUsernameAvailable($user_data[‘username’])) {
$user_data[‘username’] = $o_username.$append;
++$append;
}
Moodle version is 3.2.
Any ideas?

Thanks,
Fernando
