# The line just below this section: 'Options FollowSymLinks' may cause problems

# be set by your server administrator in a way that dissallows changing it in
# your .htaccess file. If using it causes your server to error out, comment it out (add # to
# beginning of line), reload your site in your browser and test your sef url's. If they work,
# it has been set by your server administrator and you do not need it set here.
#
# Only use one of the two SEF sections that follow. Lines that can be uncommented
# (and thus used) have only one #. Lines with two #'s should not be uncommented
# In the section that you don't use, all lines should start with #

# For Standard SEF, use the standard SEF section. You can comment out
# all of the RewriteCond lines and reduce your server's load if you
# don't have directories in your root named 'component' or 'content'
#
# If you are using a 3rd Party SEF or the Core SEF solution
# uncomment all of the lines in the '3rd Party or Core SEF' section

Moin,
oben schreibst du CMS also gross unten?

RewriteBase /cms

Wenn du extensionen drin hast musst du die Standards mit Raute/# deaktivieren und die 3rd aktivieren, vielleicht hilft das ja evtl..

#
#RewriteCond %{REQUEST_FILENAME} !-f
#RewriteCond %{REQUEST_FILENAME} !-d
#RewriteCond %{REQUEST_URI} ^(/component/option,com) [NC,OR] ##optional - see notes##
#RewriteCond %{REQUEST_URI} (/|\.htm|\.php|\.html|/[^.]*)$ [NC]
#RewriteRule ^(content/|component/) index.php
#
########## End - Joomla! core SEF Section

########## End - 3rd Party SEF Section

bzw. auch das mal probieren, je nachdem und wir schauen weiter

RewriteCond %{REQUEST_URI} ^(/component/option,com) [NC,OR] ##optional - see notes##

Moin,
SEO ist aber im Backend eingeschaltet? und du hast wirklich keine 3rd installiert? und Joomla liegt im Root? Hm dann brauchst das hier nicht aktivieren

RewriteBase /

ändern in

#RewriteBase /

aber ob das hilft?, kann sonst auf den ersten Blick nix sehen, falls obiges zutrifft, verwendest du noch etwas? OpenSEF oder ähnliches?
