Strange but for some reason, installing the newsletter module produces error below. All seems fine, with the module installed and enabled. However, error appears when clicking on the list from the newsletter administration backend – /admin/config/media/newsletter/lists message PDOException: SQLSTATE[42S02]: Base table or view not found: 1146 Table ‘database_prodd7.field_data_field_newsletter_template’ doesn’t exist: SELECT.
