Upgrading Drupal

Hi,

we are in the process of upgrading our website from Drupal 9 to Drupal 10. Upgrading via composer has worked, after some initial issues. Now, we are stuck with the database update. We have switched to PHP 8.1, but somehow, drush still finds an old PHP version and refuses to update the database. Here a copy from the CLI:

There are tons of tutorials about how to migrate a multilingual Drupal 7 website to Drupal 10 on the web.

My use case is slightly different: I need to migrate about 5000 nodes of content from a monolingual Drupal 7 webisite to a monolingual non-English Drupal 10 website. If possible I want to do it with the browser, using Migrate Drupal UI, which I've found to be excellent if the destination website is set up with English as the default language.

Hello,

Récently, since the last core update, when i try to send a newsletter, y have this message.

I have all necessary acces. I don't understand why he thinks it's an anonymous person doing something.

When I put the site in maintenance to avoid attempts by spammers, it does not change anything.
