I have a drupal 8 site where i was built a Web Service and i want to use the HTTP Basic Auth, but when i am enabling this modul, then the drupal logoff my admin user and change the permission on my pages. Also after it the login is also not available. So everytime i need to use my backup. I have only the default user login methods on the drupal page, also i disabled all extension and tried just to allow only the http basic auth, but then i got the same error.
Any idea? maybe somebody had the same problem?
