error 500 for enabling "simple seo url" within zen-cart installation

[goalsurfer]

I get a 500 internal error when enabling "ssu" in the admin panel
The error log says:

"[Sat Jun 26 20:24:11 2010] [error] [client 194.78.217.10] Request exceeded the limit of 10 internal redirects due to probable configuration error. Use 'LimitInternalRecursion' to increase the limit if necessary. Use 'LogLevel debug' to get a backtrace., referer: http://www.pulpkiosk.net/"

I don't know where to find "LimitInternalRecursion", "LogLevel debug" ...
and how do I change it then?

You should check your .htaccess in your public_html

OK, this what is in the .htaccess file:

"#### BOF SSU
Options +FollowSymLinks -MultiViews
RewriteEngine On
# Make sure to change "test_site" to the subfolder you install ZC. If you use root folder, change to: RewriteBase /
RewriteBase /zencart/

# Deny access from .htaccess
RewriteRule ^\.htaccess$ - [F]

RewriteCond %{SCRIPT_FILENAME} !-f
RewriteCond %{SCRIPT_FILENAME} !-d
RewriteRule ^(.*) index.php?/$1 [E=VAR1:$1,QSA,L]
#### EOF SSU"

Please what should be changed?
