In case you have missed deactivating the purchase code before moving site or WordPress/theme deleting it can be done in Ronneby sections. Please makes sure dfd-ronneby theme is active.
Please note that deactivation will work only on the domain where it was activated. If you changed domain name but haven’t deactivated the purchase code, please contact our support team via ticket.
Go to Ronneby section and scroll to the bottom of the page. Here you will see Question mark > click on the mark and purchase code deactivation popup will appear.
Paste your code to this form and click Deactivate theme button. Now you can use purchase code for theme activation.
