Also ich hatte bis gerade eben genau das gleiche Problem mit einerm Shared-Hosting bei 1&1. Ich habe eine Contao 3.3.7 Installation genau nach Anleitung aus dem Contaowiki vorbereitet, aber die Ordner-URLs mit „URLs umschreiben“ haben ums verrecken nicht funktiniert und die htaccess-Geschichten verstehe ich auch nicht wirklich.
Die Lösung fand mein Brüderchen hier bei Stackoverflow >>>
Diese zeilen habe ich einfach am Ende der htaccess vor </IfModule> ergänzt
Code:
Options +FollowSymLinks -MultiViews
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?$1 [L,QSA]
RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\s(.*)/index\.php [NC]
RewriteRule ^ %1 [R=301,L]
und die Zeilen
Code:
# RewriteCond %{REQUEST_FILENAME} !-f
# RewriteRule .*\.html$ index.php [L]
auskommentiert, da das sonst doppelt gemoppelt wäre.
Es scheint alles zu funktionieren. Was denkt ihr?
Hier nochmal die gesamte htaccess ab „URL rewriting“
Code:
##
# URL rewriting
##
<IfModule mod_rewrite.c>
RewriteEngine On
##
# Change the RewriteBase if your Contao installation is in a subdirectoy and
# the rewrite rules are not working properly. Usage examples:
#
# RewriteBase /contao-3.0.0
# RewriteBase /path/to/contao
#
# Depending on your server, you might have to remove the line entirely.
##
RewriteBase /
##
# Uncomment the following lines to add "www." to the domain:
#
# RewriteCond %{HTTP_HOST} ^example\.com$ [NC]
# RewriteRule (.*) http://www.example.com/$1 [R=301,L]
#
# Uncomment the following lines to remove "www." from the domain:
#
# RewriteCond %{HTTP_HOST} ^www\.example\.com$ [NC]
# RewriteRule (.*) http://example.com/$1 [R=301,L]
#
# Make sure to replace "example.com" with your domain name.
##
##
# If you cannot use mod_deflate, uncomment the following lines to load a
# compressed .gz version of the aggregated Contao JavaScript and CSS files.
##
#AddEncoding gzip .gz
#<FilesMatch "\.js\.gz$">
# AddType "application/javascript" .gz
#</FilesMatch>
#<FilesMatch "\.css\.gz$">
# AddType "text/css" .gz
#</FilesMatch>
#RewriteCond %{HTTP:Accept-encoding} gzip
#RewriteCond %{REQUEST_FILENAME} \.(js|css)$
#RewriteCond %{REQUEST_FILENAME}.gz -f
#RewriteRule ^(.*)$ $1.gz [QSA,L]
##
# By default, Contao adds ".html" to the generated URLs to simulate static
# HTML documents. If you change the URL suffix in the back end settings, make
# sure to change it here accordingly!
#
# RewriteRule .*\.html$ index.php [L] # URL suffix .html
# RewriteRule .*\.txt$ index.php [L] # URL suffix .txt
# RewriteRule .*\.json$ index.php [L] # URL suffix .json
#
# If you do not want to use an URL suffix at all, you have to add a third
# line to prevent URLs that point to folders from being rewritten (see #4031).
#
# RewriteCond %{REQUEST_FILENAME} !-d
# RewriteRule .* index.php [L]
#
# If you are using mod_cache, it is recommended to use the RewriteRule below,
# which adds the query string to the internal URL:
#
# RewriteRule (.*\.html)$ index.php/$1 [L]
#
# Note that not all environments support mod_rewrite and mod_cache.
##
#RewriteCond %{REQUEST_FILENAME} !\.(htm|php|js|css|htc|png|gif|jpe?g|ico|xml|csv|txt|swf|flv|mp4|webm|ogv|mp3|ogg|oga|eot|otf|tt[cf]|woff|svg|svgz|pdf|gz)$
# RewriteCond %{REQUEST_FILENAME} !-f
# RewriteRule .*\.html$ index.php [L]
##
# The following rules are required if you want to pass the language as first
# URL parameter (added in Contao 2.11). The first rule rewrites the empty URL
# to the front end controller, the second one adds a missing trailing slash.
##
RewriteRule ^[a-z]{2}(\-[A-Z]{2})?/$ index.php [L]
RewriteRule ^([a-z]{2}(\-[A-Z]{2})?)$ $1/ [R=301,L]
Options +FollowSymLinks -MultiViews
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?$1 [L,QSA]
RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\s(.*)/index\.php [NC]
RewriteRule ^ %1 [R=301,L]
</IfModule>
Fehler bei Installation bei 1&1

. 1&1 ist also wohl ausnahmsweise mal außen vor.
