I am using OctoberCMS latest version and i have installed Flexi contact plugin https://octobercms.com/index.php/plugin/laminsanneh-flexicontact and i have configured contact form.

But whenever i press Submit button, i m keep getting an error message in console saying

NetworkError: 406 Not Acceptable

However, plugin works fine.. This happens to one of the themes which OctoberCMS provides as well .. So i guess its common issue ..

Can someone guide me how to solve this ?

Thanks
