Foreman upgrade 1.21 and Katello 3.11

I have successfully upgraded Foreman 1.20.2 → 1.21 and Katello 3.10–>3.11 on OS Centos 7.
Problem 1.: When I select a Location in GUI it appears all in white (no left or upset task-bar):


Problem2:
On Katello server:
foreman-proxy-certs-generate --foreman-proxy-fqdn smartproxy.com --certs-update-all --certs-tar ~/smartproxy.com-certs.tar
ERROR: Unrecognised option ‘–certs-update-all’

On Smart- proxy:
foreman-installer --scenario foreman-proxy-content --upgrade --foreman-proxy-content-certs-tar ~/smartproxy.com-certs.tar --certs-update-all --certs-regenerate true --certs-deploy true
ERROR: Unrecognised option ‘–foreman-proxy-content-certs-tar’

Expected outcome:

Foreman and Proxy versions:

Foreman and Proxy plugin versions:

Other relevant data:
[e.g. logs from Foreman and/or the Proxy, modified templates, commands issued, etc]
(for logs, surround with three back-ticks to get proper formatting, e.g.)

logs

The first issue has been reported at Bug #26394: when changing location user looses all navigation menus - Foreman and hopefully the @ui_ux team will find a fix for it in time for 1.21.1.

Hi…i have recreated the locations without parent and it is working now.

Problem2:
On Katello server:
Successful started the foreman-proxy-certs-generate without --certs-update-all.

On Smart- proxy:
Successful started foreman-installer --scenario foreman-proxy-content with --certs-tar-file instead of –foreman-proxy-content-certs-tar.
