Clear installation on Ubuntu server 18.04, theme preview blank

Your software
My Mautic version is:2.16.2
My PHP version is: 7.2.24

Your problem
My problem is:Installation worked fine, with no problem. After first login when i go on Components, Landing Pages, i see list of all theme, but dont show any image. If i try to use Preview on 1 theme, i see a blank page.

These errors are showing in the log:No error, except one, but think no correlation on this problem :

  • [2020-05-11 14:46:04] mautic.ERROR: SCHEMA ERROR: An exception occurred while executing ‘SELECT f.alias, f.is_unique_identifer as is_unique, f.type, f.object FROM lead_fields f WHERE f.object = ‘lead’ ORDER BY f.field_order ASC’: SQLSTATE[42S02]: Base table or view not found: 1146 Table ‘mautic.lead_fields’ doesn’t exist *

Steps I have tried to fix the problem:verify auth and owner path /var/www/mautic/themes, is the same on all folder: drwxr-xr-x www-data www-data.
Obviously, button Builder dont work.
