Contact id quicksearch broken
Contact id quicksearch has broken in 5.67.3, albeit occasionally. User cannot locate any contacts by id at all, and using Drupal 'masquerade I verified this to be the case. The fix was to run the 'Cleanup Caches' option. What may be a clue is that this system uses ACLs and although this user would have been restricted by ACLs she would have had access to the contacts she was searching for. As an administrator I could see the contacts when she couldn't which does seem to point to ACLs as the problem.
