I have buyed your theme martfury and I would like to know how could I insert it the Item Purchase Code to have all the options.
I note that I already install and also import the demo
Please check the theme documentation hopefully you will get necessary support.
Otherwise the best way to get the support is Contact your purchased theme Author. How to Contact Author and let them know. Don’t worry just contact theme Author. theme Author will be very happy to assist you.
Also you can check your theme Options hope you will get license registration option there.
