I am using your newsletter plugin since quite some time, the version I first installed on my site was Version 3.0.7. I am currently using latest 3.5.9 version.
I am facing this error whenever I fill in my email address in newsletter form and hit subscribe button. It takes me to following URL:
And shows following error:
Fatal error: Class ‘NewsletterSubscription’ not found in /hermes/bosoraweb111/b2738/…./wp-content/plugins/newsletter/do/subscribe.php on line 12
I have tried downgrading to version 3.0.7 which I had in my backups, but the error still exists. I cannot find any help online to fix this issue. Please help.
