I was trying to install this plugin and I'm always getting this message:
"An error has occurred
The newsletter to Which You Are Trying to subscribe does not exist in Our records."
This is the link that appears: myurl. com /?wpr-optin=1
I've tried searching the Internet help for this error and still found nothing, though I've verified that I'm not the only one to receive this error.
Any idea for the cause of the problem?
Thanks in advanced
