Error during installation of Jollyness theme

My Drupal site was working perfectly before the Jollyness them was installed ! After installation showed successful... received this error: Fatal error: Cannot redeclare _field_info_field_cache() (previously declared in /srv/bindings/4f8b9da1ba1647139c3f99fbf8ca9bd5/code/modules/field/field.info.inc:16) in /srv/bindings/4f8b9da1ba1647139c3f99fbf8ca9bd5/code/sites/all/modules/Drupal_Jollyness/Demo/modules/field/field.info.inc on line 32 Also, this error is showing on all pages: PDOException: SQLSTATE[42S02]: Base table or view not found: 1146 Table 'pantheon.media_type' doesn't exist: SELECT mt.* FROM {media_type} mt ORDER BY weight ASC; Array ( ) in media_type_get_types() (line 134 of /srv/bindings/4f8b9da1ba1647139c3f99fbf8ca9bd5/code/sites/all/modules/Drupal_Jollyness/Demo/sites/all/modules/media/includes/media.types.inc). This is not a pleasant experience.
