Unable to open flarum after upgrade

Th0mC

Hi
I've just updated my flarum instance.
After execution composer update
I get the following message
Carbon 1 is deprecated, see how to migrate to Carbon 2. https://carbon.nesbot.com/docs/#api-carbon-2 You can run './vendor/bin/upgrade-carbon' to get help in updating carbon and other frameworks and libraries that depend on it.

So I execute
**./vendor/bin/upgrade-carbon** Do you want us to try the following upgrade:
- nesbot/carbon: ^2.0.0 [Y/N] Y Loading composer repositories with package information Updating dependencies (including require-dev) Nothing to install or update Package flagrow/console is abandoned, you should avoid using it. Use fof/console instead. Package flagrow/user-directory is abandoned, you should avoid using it. Use fof/user-directory instead. Generating autoload files

Tried to flush the cache

php flarum cache:clear
Clearing the cache...

And now I have

Une erreur est survenue lors du chargement de la page.
An error occurs during loading of the page

Please help 😉
Thx

Th0mC The Carbon upgrade isn't needed, that's merely a suggestion, and you didn't update it either, it just tested the update.

Try updating flarum/core, as beta 8.2 fixed the FontAwesome issue. See https://discuss.flarum.org/d/17745-flarum-0-1-0-beta-8-released/293. You should no longer need the workaround.
