The theme has been updated with new features in the theme setting.
There are some customers wonder why I cannot save setting? why receive the message Sorry! Payment Gateway: Submit Form is not available for this item!? in the checkout page even the submit form has been enabled in Traveler Settings > Payment Options.
Please note: That is normal setting and it just display like that. In order to make the theme run the best, you need to increase the server’s parameters according to our requirements, especially the PHP Max Input Var to save the Traveler Setting.
After make sure your server meet our requirements, please go to Traveler Settings section and click on Save Changes button to update all settings.
