Unknown column 'content_translation_source' error

There is currently a common issue after enabling “CERN Landing pages” module. Due dependencies some entity translation module is also enabled but it doesn’t get fully configured.

While editing or creating nodes you might encouter an error like:

   `Drupal\Core\Entity\EntityStorageException: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'content_translation_source' in 'field list'`

The workaround to resolve this is, got to Configuration -> Content language and translation
once there without changing anything just click on “Save” button.

This will create missing tables and should resolve the problem.
