After Upgrading to Drupal 7.50 (or Later), I Get Missing Module Warnings


After upgrading to Drupal 7.50 (or later), you start seeing red error messages that read "The following module is missing from the file system...".

Drupal 7.50 began scanning more carefully for module and theme files, including files for modules and themes that had been disabled, but not uninstalled.  Unfortunately, many Drupal site administrators have disabled and deleted modules in the past without running the uninstall process, and once the module has been deleted, you no longer have a way to uninstall it.
