Broken Magento 2 - CSS not loading?

[caos989]

Hi,

I made a mistake today with my test installation.

Seems like the CSS is not loading correctly.

I tried to install an extension and there was a error like: can't delete directory XXX so I just renamed it was deleted from the system

Right now I see the frontend and backend with broken layouts.

Is it possible to fix this somehow or shoud I reinstall it?

in my exception.log I have this:

[2022-03-27 18:12:46] main.CRITICAL: The contents from the "/home/seedsat/public_html/magento2-ub3/pub/static/adminhtml/Magento/backend/de_AT/mage/requirejs/mixins.js" file can't be read.

This files don't exist

In my Webbrowser I get the status 304

I tried:

php bin/magento setup:upgrade
php bin/magento setup:di:compile
php bin/magento setup:static-content:deploy -f
php bin/magento cache:clean
php bin/magento cache:flush
php bin/magento indexer:reindex

and I tried to set the permissions correctly.

I copied all files from

pub/static/adminhtml/Magento/backend/en_US

to:

pub/static/adminhtml/Magento/backend/de_DE

and
pub/static/adminhtml/Magento/backend/de_AT

this repaired the backend again.

I did the same for my theme

from:

/pub/static/frontend/Smartwave/porto/en_US
to:

/pub/static/frontend/Smartwave/porto/de_DE

Can somebody tell me why this files was deleted?
