Admin settings do not save correctly

[azbulutlu]

Describe the bug

Some of the admin settings do not work correctly on a fresh install.

Context

• Hardware: VPS bought online
• YunoHost version: 4.3.6.3
• I have access to my server: Through SSH
• Are you in a special context or did you perform some particular tweaking on your YunoHost instance?: no
• Using, or trying to install package version/branch: 11.2

Steps to reproduce

• Fresh install of pixelfed.
• enabled admin interface as directed.

Expected behavior

Some settings can be changed, but others do not. (e.g. Branding instance title, long and short descriptions, about page headline, custom CSS)

The settings seems to be save, but when admin panel is refreshed it is clear changes were not reflected.

notes:

this is also referenced in the following issue upstream but putting it here as well as many of the cases mentioned seems to be yunohost related.

Some users can get partial fixes by chmoding some folders but not sure if this is the correct workaround.
