Hello,

I am testing your plugin Usergroup Selector. Thank you for this.

The field is shown and the user is saved with the groups I selected. But: I get this message while registration: Catchable fatal error: Object of class stdClass could not be converted to string in /joomla/libraries/joomla/form/fields/checkboxes.php on line 161

I just found out something.
One sees the error message described above only if another error occurs.

I have tested the extension locally. No e-mail function is installed here. So I get an error, that no email could be send. Beside this error I saw the here mentioned error.

I have just installed the extension on another computer with active email function. Here you will be forwarded immediately while registration. That's why you can not see the here mentioned error.
