I'm implementing the membership plugin, have just upgraded to most recent version. Sometimes the plugin is processing shortcodes (no shortcode displays) and other times it displays the shortcode. It appears to show the shortcode (and content) when the security allows the member to see the content. I think it should show the content but not the shortcode.
These are shortcodes set up to do nothing other than hide selected content based on levels. They are not gravity forms or other processed shortcodes. This could be part of the issue (no shortcode definition to process it).
