We're having an issue with saving Particle widgets in the Widgets manager. We are using Wordpress 4.9.5, Gantry 5.4.23, and Interstellar 1.0.8. PHP is 7.0.29 and MySQL is 10.1.33-MariaDB. Making a change to a widget does not result in the Save button being enabled and allowing the widget to be saved. Changing the Custom Classes field, however, does. While it's a workaround, it's a bit clunky. We've searched for a solution, and have come up empty-handed. Any help resolving this would be appreciated.
