Thanks for your answers. The SSL certificate had not expired.
I fixed the problem with the help of my web host: the website’s URL was configured in WordPress with the “.fr” TLD when it should have been “.org”. It seems that the “.fr” one just redirects to the “.org” so it messed up something somewhere…

Hi, thanks for your answer.

Renaming the plugins folder didn’t change a thing, but I’ve noticed something else: images aren’t loaded because of a “mixed content” error, where images are apparently loaded from http URL when the site is accessed in https.
But I don’t know why it would mess up the login, and I currently can’t find a way to solve that problem.

Here is the website URL: https://mackid.legtux.org
