I Just bought your “sweet date” theme and installed. Then try to set it up.
The Sign-up button in registration form not working.
And I try to following your guide to change the search form color in KB, it is not working at all.
Please check the theme documentation hopefully you will get necessary support in documentation. Hope in documentation you will get how to import demo. Also you can check your theme Option if you find anything related to the issue. If you have still problem with the theme then The best way to get the support is Contact your purchased Theme Author.
Don’t worry just contact Author. Author will be very happy to assist you.
