So I decided to run some neglected updates today (animaltree.org is the site), and when running the security update for views I killed the site. I attempted to fix the problem through drush rr and I did get a bit further but I am now stuck. I can't clear the cache, specifically the menu cache, without running into this error:
Fatal error: Class 'EntityDefaultMetadataController' not found in path_to_drupal/sites/all/modules/field_collection/field_collection.info.inc on line 8
I can't run a restore without being halted by the same error message either. Any ideas to help get past this and what I screwed up so I don't do this again?
