Steps to reproduce the issue

When creating or updating viewlevels (within the administration site), I get this error :
L'enregistrement a échoué avec l'erreur suivante : Unknown column 'metakey' in 'field list' SQL=UPDATE u1vtf_viewlevels SET title='Pharmacie',ordering='0',rules='[10,11,14,8]',metakey='' WHERE id='8'

Seems that a columnt metakey should exist in table viewlevels, but it's not the case.

Expected result

Should be able to create or modifiy viewlevels ...

Actual result

Error when create or modify viewlevels
