Invalid argument /class-ms-addon-profilefields.php on line 503

On my register page for a paid membership I am getting this error on the bottom of the page: Warning: Invalid argument supplied for foreach() in /home/content/35/11098935/html/wp-content/plugins/membership/app/addon/profilefields/class-ms-addon-profilefields.php on line 503

Also there is no place to add my credit card info during the registration process...
