Symfony

Hello,

There are some missing translation for Norwegian Nynorsk (nn). These should be added in branch 4.4.
See symfony/symfony#38710 for details and this page for an example.

These are the files that should be updated:

• [src/Symfony/Component/Security/Core/Resources/translations/security.nn.xlf](https://github.com/symfo

The /about page is quite old and some things need to be updated:

• 3rd party libraries: we have to update the list
• the link on "helping wallabag" tab (an issue lists all our needs) is wrong
• the "who is behind wallabag" tab is old: my website is wrong ... and @Kdecherf is missing.

Sylius version affected: v1.4.4

Description

Sylius says the category is used and cannot be removed, when we try to remove an empty category.

We figured out that we had some products with the taxon as "Main Taxon".

Steps to reproduce

1. Add a taxon, keep it empty of products.
2. Update a product to use the newly created taxon as Main taxon.
3. Try to remove the taxo
