permalinks and 403-error

hi,

i´m coming from austria and i have a little problem with my new blog. i installed my blog in root on http://www.xtase.net and then i activated permalinks, but after that i get an 403-error.

i see that there are some other probleme with permalinks, but i didn´t find any other posting with the same problem i have.

My .htaccess look like them:

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress

I did a chmod 666 on the .htaccess-file.

mod_rewrite is enabled on server (all-inkl.com). i have also another blog, which is in http://www.xtase.net/blog/, this blog runs without any permalink-problems.

i will be very happy, if there is anyone who can help me 😉

bye
andy
