Hi,
I have the same problem. So i tried to reinstall the new version of the plugin and when i activate it, i see this message:
Fatal error: Call to a member function getValue() on a non-object in /web/sites/clarahost-fr/2/246/184162/public/www/wp-content/plugins/wysija-newsletters-2/core/base.php on line 1486
..and my front-end becomes white… so i have to deactivate wysija and then it works ..
Can you help?
