Error when signing up

Hello again I have been testing out the payplan plugin. I made a test user and signed up at - http://chicagosnexttopmodel.com/dev/gaze/index.php/membership

I use the free forever plan ( its the only one setup)

When I sign a user up it works but the errors below appear before the registration successful page

Notice: Use of undefined constant JPATH_COMPONENT - assumed 'JPATH_COMPONENT' in /home/nexttopmodel/public_html/dev/gaze/libraries/src/MVC/Model/FormModel.php on line 222

Notice: Use of undefined constant JPATH_COMPONENT - assumed 'JPATH_COMPONENT' in /home/nexttopmodel/public_html/dev/gaze/libraries/src/MVC/Model/FormModel.php on line 223

Also I never receive an email for the user to approve the account. I checked the spam box and all.

thanks
