Have you ensured that your storage folder and all its subfolders are writeable? This could be a permissions problem writing the log entry for the http no found exception when your route fails.

For testing I set storage (and all subfolders+files) to chmod 777. Still same Problem :-(

php version?

it´s version 5.5

Refered to this https://stackoverflow.com/questions/17228936/laravel-default-htaccess-file-will-not-work

I added a slash to last line: RewriteRule ^ /index.php [L]

It fixed the internal Server Errors but not the redirect Loop

Try adding this before the rewrite rules.

RewriteBase /

I have found this to be necessary on some hosts.

@spekkionu I´ve added the line - still getting a redirect Loop when typing a url to a folder (e.g. mydomain/images)

<IfModule mod_rewrite.c>
    <IfModule mod_negotiation.c>
        Options -MultiViews
    </IfModule>

    RewriteEngine On
    RewriteBase /

    # Redirect Trailing Slashes...
    RewriteRule ^(.*)/$ /$1 [L,R=301]

    # Handle Front Controller...
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteRule ^ /index.php [L]
</IfModule>
