I have the latest version 8.6.0 of WP Newsletter with the import/export addon activated, however clicking the import/export item from the drop-down menu invites me to install the addon again, even though the addon is already installed. I also tried on another WordPress installation and the problem is the same. Give me hope, thanks.
Hi Michele,
yes it is activated. There is an expired Pro license on the site and I fear that the problem is that. Now I have to figure out how to deactivate the license and reactivate it with a new free account.
try to do the following: go to your account page on our website, find the license and click on the regenerate button. Then copy paste the new license code inside the plugin in Settings> General Settings.
