I am attempting to integrate this plugin to my website (http://www.beecaveyoga.com) but when subscribers click on the confirmation link in their email it takes them to the webpage indicating their subscription has bee confirmed. However, the following message is also there:
WARNING - Weaver II is not designed to use sidebar.php directly.
This message is most likely caused by an invalid child theme calling the standard WordPress function get_sidebar('sidebar-name') with an invalid sidebar-name. It is also possible this is called by an incompatible plugin.
