I took a closer look into the code, especially function language_redirect_is_login().
Found the solution:
https://www.mydomain.com/subfolderWPisInstalled/wp-login.php does not work but

https://www.mydomain.com/en/wp-login.php works.

So the “virtual” subfolder has to go into the url.

What I do not understand is the fact that it worked with the subfolder when “force login” plugin was active.

Hello Bjoerne,
Thanks for your answer!
The problem still exists. One hint (that did not help me to find solution yet): When I delete the plugin from the folder, login thereafter and add it to the folder again, at least the logout works. So, I think this has something to do with plugin registration in WP but no idea how to fix it

More information that might help:
Current solution to get to the admin panel is to delete the language redirect plugin from plugin folder. I can then reach admin as always (/wp-admin) and once logged in, I add the plugin again. During that period site is off (not reachable over domain).
Thanks
