I have the same issue I submitted a contact form over at https://codeasily.com/ with this issue. Hopefully we see a fix for this soon. It’s related to JQuery and if you need this to work NOW you can use the “Enable jQuery Migrate Helper” WordPress Plugin to get it working again. Just install the plugin access it under “Tools” in WordPress an set the “jQuery Version” to “Legacy XXXX”. As the plugin will tell you….this is NOT a solution, only a work around until the Gmedia Plugin code is updated to use a newer version of JQuery.
