After updating to the latest release, July 26th, the week calendar has disappeared from my site. It does not display on the actual week calendar page (http://www.hills4thrills.com/activities/week) and the week widget is also not displaying. It just shows the shortcode in its place (see screenshot).
When I viewed your System Info, I didn’t see Events Calendar Pro in the list. Can you confirm that it is installed and activated? Week view is limited to ECP.
