Hi Maxime, I don’t have many plugins installed, but might be related to this: https://essential-addons.com/elementor/docs/login-register-form/
I will do some tests when I have time, but I can’t deactivate it forever because I use it for the whole website’s UI.
I managed to log in meanwhile via my hosting provider and de-activated the plugin, so I can now log back in using the default links and everything seems to work just fine like that. But I would still want to re-activate the plugin and use it, any ideas how I can make it work?
