Hallo Hans-Gerd, danke für deine rasche Rückmeldung.
Nein, das Problem habe ich schon länger….
mein .htaccess datei ist so aufgebaut:
ErrorDocument 401 /401.php
RewriteEngine On
# HTTPS-Redirect nur wenn nicht HTTPS
RewriteCond %{HTTP:X-Forwarded-Proto} !https
RewriteCond %{HTTPS} !=on
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
<If "%{HTTPS} == 'on'">
Header always set Strict-Transport-Security "max-age=31536000; includeSubDomains"
Header always set Content-Security-Policy "upgrade-insecure-requests;"
</If>
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
