I have been having issues. When trying to send out email with the plugin it will kick back an error code. Under the “New Posts” tab I can test and it will send to my test account. If I press the SendNow I get the following error:
Fatal error: Call to undefined method NewsletterFeed::get_prefix() in (removed for security…)www.revbiga.com/wp-content/plugins/newsletter-feed/feed.php on line 442
It will not send to my subscription list. Please advise.
