From MoodleDocs

The most likely cause of this error is that the 'version' key is missing from your configuration dictionary.

Steps to fix:

  • Open <moodleinstalldir>/version.php
  • Find the value in $version
  • Open 'mdl_config' in database manager
  • Insert key after last entry with name = 'version' and value = <value found in version.php>
