Once installed The Fox theme, you’ll have to register that site with a purchase code. However, sometimes you can’t access to your website somehow but you still want to revoke the purchase code to use for another site. In that case, please visit WiThemes Purchase Code Management Site.
Step 1: Visit WiThemes License Site.
Step 2: Login with username is your ThemeForest username and password is your purchase code.
Step 3: Go to Dashboard > Purchase Codes. You’ll find your purchase code and your site info there.
Step 4: Click “Trash” to delete it.
Now, your purchase code has been revoked manually and you’ll be able to use that purchase code for any other site you want to.
