Hallo,
ich habe da 2 Dateien erhalten. Die “htaccess.txt” sieht so aus:
[code]##
@package Joomla
@copyright Copyright © 2005 - 2012 Open Source Matters. All rights reserved.
@license GNU General Public License version 2 or later; see LICENSE.txt
READ THIS COMPLETELY IF YOU CHOOSE TO USE THIS FILE!
The line just below this section: ‘Options +FollowSymLinks’ may cause problems
with some server configurations. It is required for use of mod_rewrite, but may already
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.
Can be commented out if causes errors, see notes above.
Options +FollowSymLinks
Mod_rewrite in use.
RewriteEngine On
Begin - Rewrite rules to block out some common exploits.
If you experience problems on your site block out the operations listed below
This attempts to block the most common type of exploit attempts to Joomla!
Block out any script trying to base64_encode data within the URL.
RewriteCond %{QUERY_STRING} base64_encode[^(]([^)]) [OR]
Block out any script that includes a tag in URL.
RewriteCond %{QUERY_STRING} (<|%3C)([^s]s)+cript.(>|%3E) [NC,OR]
Block out any script trying to set a PHP GLOBALS variable via URL.
RewriteCond %{QUERY_STRING} GLOBALS(=|[|%[0-9A-Z]{0,2}) [OR]
Block out any script trying to modify a _REQUEST variable via URL.
RewriteCond %{QUERY_STRING} _REQUEST(=|[|%[0-9A-Z]{0,2})
Return 403 Forbidden header and show the content of the root homepage
RewriteRule .* index.php [F]
End - Rewrite rules to block out some common exploits.
Begin - Custom redirects
If you need to redirect some pages, or set a canonical non-www to
www redirect (or vice versa), place that code here. Ensure those
redirects use the correct RewriteRule syntax and the [R=301,L] flags.
End - Custom redirects
Uncomment following line if your webserver’s URL
is not directly related to physical file paths.
Update Your Joomla! Directory (just / for root).
RewriteBase /
Begin - Joomla! core SEF Section.
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
If the requested path and file is not /index.php and the request
has not already been internally rewritten to the index.php script
RewriteCond %{REQUEST_URI} !^/index.php
and the request is for something within the component folder,
or for the site root, or for an extensionless URL, or the
requested URL ends with one of the listed extensions
RewriteCond %{REQUEST_URI} /component/|(/[^.]*|.(php|html?|feed|pdf|vcf|raw))$ [NC]
and the requested path and file doesn’t directly match a physical file
RewriteCond %{REQUEST_FILENAME} !-f
and the requested path and file doesn’t directly match a physical folder
RewriteCond %{REQUEST_FILENAME} !-d
internally rewrite the request to the index.php script
RewriteRule .* index.php [L]
End - Joomla! core SEF Section.

Die “.htaccess” so:

Ich habe mich da zwar schon durchgelesen, aber ich komme irgendwie nicht auf den Fehler. 
Kommentiere die Zeile mal aus und probier’s dann erneut…
