Support [NEW] Problems with Index.php!

[iCrashMix]

Hey, I have installed fresh version of xenForo v2.2.11 and how do I remove index.php from the link? There is an option called "Use full friendly URLs" and it doesn't do anything for me because it doesn't work or when I'm on the start page and then go to another subpage for example, I get this error message that it wasn't found. (if you ever need my link for any reason, you can find it here: SimpleMine Forum)

.htaccess

ErrorDocument 401 default
ErrorDocument 403 default
ErrorDocument 404 default
ErrorDocument 405 default
ErrorDocument 406 default
ErrorDocument 500 default
ErrorDocument 501 default
ErrorDocument 503 default

<IfModule mod_rewrite.c>
    RewriteEngine On

    RewriteCond %{REQUEST_FILENAME} -f [OR]
    RewriteCond %{REQUEST_FILENAME} -l [OR]
    RewriteCond %{REQUEST_FILENAME} -d
    RewriteRule ^.*$ - [NC,L]
    RewriteRule ^(data/|js/|styles/|install/|favicon\.ico|crossdomain\.xml|robots\.txt) - [NC,L]
    RewriteRule ^.*$ index.php [NC,L]
</IfModule>

Ok I have entered with the text in the .htaccess respectively the remaining text of xenForo belongs deleted and then I have replaced the whole by this. And just this option activated by "Use fully friendly URLs" and it unfortunately does not work, so at the latest only when I switch to another unterseite.

mod_rewrite must be enabled on your host
admin.php?options/groups/seo/

Somehow it's just incomprehensible that it doesn't work even though I have everything set 100% correctly. By the way the forum was also freshly reinstalled. And mod_rewrite is somehow already enabled. See pictures at:
