@tab: habe die htaccess entsprechend geändert, und nun funktioniert es. Habe die untersten Zeilen nach oben gesetzt und auch die "http to https"-Zeilen auskommentiert. Hier nochmal die geänderte htaccess. Soll ich die auskommentierten Zeilen löschen?
Code:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{HTTP_HOST} ^plusweb\.se$
RewriteRule (.*) https://www.plusweb.se/$1 [R=301,L]
<IfModule mod_headers.c>
# Assets in /assets and /bundles either contain a hash in their filename
# or are called with a ?version suffix, therefore cache them for 1 year.
RewriteRule ^(assets|bundles)/ - [ENV=CONTAO_ASSETS:true]
Header set Cache-Control "max-age=31536000" env=CONTAO_ASSETS
# Allow CORS on the Contao TinyMCE skin.
RewriteRule ^assets/tinymce4/js/skins/contao/fonts/ - [ENV=CONTAO_TINYMCE_SKIN:true]
Header set Access-Control-Allow-Origin "*" env=CONTAO_TINYMCE_SKIN
</IfModule>
# Determine the RewriteBase automatically and set it as environment variable.
# If you are using Apache aliases to do mass virtual hosting or installed the
# project in a subdirectory, the base path will be prepended to allow proper
# resolution of the index.php file and to redirect to the correct URI. It will
# work in environments without path prefix as well, providing a safe, one-size
# fits all solution. But as you do not need it in this case, you can comment
# the following 2 lines to eliminate the overhead.
RewriteCond %{REQUEST_URI}::$1 ^(/.+)/(.*)::\2$
RewriteRule ^(.*) - [E=BASE:%1]
# Sets the HTTP_AUTHORIZATION header removed by Apache
RewriteCond %{HTTP:Authorization} .
RewriteRule ^ - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
# Redirect to URI without front controller to prevent duplicate content
# (with and without `/index.php`). Only do this redirect on the initial
# rewrite by Apache and not on subsequent cycles. Otherwise we would get an
# endless redirect loop (request -> rewrite to front controller ->
# redirect -> request -> ...).
# So in case you get a "too many redirects" error or you always get redirected
# to the start page because your Apache does not expose the REDIRECT_STATUS
# environment variable, you have 2 choices:
# - disable this feature by commenting the following 2 lines or
# - use Apache >= 2.3.9 and replace all L flags by END flags and remove the
# following RewriteCond (best solution)
RewriteCond %{ENV:REDIRECT_STATUS} ^$
RewriteRule ^index\.php(?:/(.*)|$) %{ENV:BASE}/$1 [R=301,L]
# If the requested filename exists, simply serve it.
# We only want to let Apache serve files and not directories.
RewriteCond %{REQUEST_FILENAME} -f
RewriteRule ^ - [L]
# Rewrite all other queries to the front controller.
RewriteRule ^ %{ENV:BASE}/index.php [L]
</IfModule>
<IfModule !mod_rewrite.c>
<IfModule mod_alias.c>
# When mod_rewrite is not available, we instruct a temporary redirect of
# the start page to the front controller explicitly so that the website
# and the generated links can still be used.
RedirectMatch 302 ^/$ /index.php/
# RedirectTemp cannot be used instead
</IfModule>
</IfModule>
#RewriteCond %{HTTP_HOST} ^plusweb\.plusweb\.se$
#RewriteRule ^/?$ "http\:\/\/plusweb\.se\/plusweb\/\^\/\$" [R=301,L]
#<IfModule mod_rewrite.c>
