While adding context to a variant in Drupal Panels, I experienced an error and cannot resolve. When I navigate to Structure > Pages > edit (Node template), select "Node panelizer" > "Context" and try to add a context by clicking the "Add context" button, the error is shown (please see attached image).

Using:
Drupal 7.23
Install profile: Commons (commons-7.x-3.2)
Ctools 7.x-1.3
Panelizer 7.x-3.1
Panels 7.x-3.3

There seems to be some update that removes the following file
sites/all/modules/ctools/page_manager/plugins/cache/page_manager_context.inc

If you replace this file, context works again.

Thanks bsarchive - I was using the distro "Drupal Commons" but decided to scrub it as it has lots of issues to be used for a production site.
