I'm working with Subscribe2, wich does not allow email template customization --> I like your plugin, but can't get it to work properly :
On the settings page, I have the following pbs :
- the image I uploaded in the template header is not taken into account
- changes I make in the email Header and email body are not are not saved.
- the email preview link displays the following error :
Fatal error: Call to undefined method s2class_upgrade::get_usermeta_keyname() in /homez.109/parolenu/www/AAPO-test/wp-content/plugins/subscribe2/classes/class-s2-upgrade.php on line 292"
Can you please help ?
