Hello,
Thank you for your interest in my problem.
I managed to resolve it. I deleted all the extra Newsletter plugins (from the paid version), upgraded my PHP to 8.1, and now I can see the Import/export plugin.
Hello,
thank you fot your reply. I am using Newsletter 8.6.4, and yes, the Addon MAnager ans IMport/export free addon are installed. I cannot see the Import/Export tool under Subscribers. It goes from Subcribers, Lists and Settings.
hello Stefano, Thank you for your reply, and excuse my delayed answer. I did the screenshot but I can't paste it here. Can I use another way to send it to you. Thank you for your support. Pierre Souchar
