Wartungsmodus erzeugt zu viele Weiterleitungen

Hallo, ich kann kein Update anstoßen, da der Wartungsmodus zu viele Weiterleitungen erzeugt. In den Shopeinstellungen steht bei Host: http://www.meinedomain.de und die htaccess sieht so aus: [code]
RewriteEngine on

#RewriteBase /shopware/

Https config for the backend

#RewriteCond %{HTTPS} !=on
#RewriteRule backend/(.*) https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

RewriteRule shopware.dll shopware.php
RewriteRule files/documents/.* engine [NC,L]
RewriteRule backend/media/(.*) media/$1 [NC,L]

RewriteCond %{REQUEST_URI} !(/(engine|files|templates|themes|web)/)
RewriteCond %{REQUEST_URI} !(/media/(archive|banner|image|music|pdf|unknown|video)/)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ shopware.php [PT,L,QSA]

Fix missing authorization-header on fast_cgi installations

RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization},L]
