I activated the My_calendar plugin. It seems to be working in the widget section, and when I place the [mycalendar]shortcode in a page, it displays fine. However - I cannot see it in the admin sidebar, or edit it, or input any events. When I try to click on the settings link for the plugin, or the help link, I get the error: You do not have permission to access this plugin feature. I looked in the capabilities for Access Manager and I did not see anything the resembles my_calendar - or how I could edit the Admin or Super Admin access roles.
Hope someone has suggestions on how to get this going.
