Hi, guys, I have Zencart v1.3.8,
I installed Module Manager (and its working), and I installed Simple SEO URL Version: 3.5.8.

After finishing the installation, my index page works fine, but I get 500 Internal Server Error on all other pages (links).
The http adresses are good too, for example: for category it would give http://www.MySite/cake-c-3.

I checked MySite/admin configuration, its the same as people suggest in the forum.
I was missing cache/.... directories, so i added them
I checked my htacces in root directory and it seems fine, it reads:

<IfModule mod_security.c>
SecFilterEngine Off
SecFilterScanPOST Off
</IfModule>

#### BOF SSU
Options +FollowSymLinks
RewriteEngine On
# Change "/zencart/ to the correct setting
# if your site is located at root folder, then you should have RewriteBase /
# Go to your include/configure.php, this value should be the same with the value of DIR_WS_CATALOG
RewriteBase /www.*******.com/

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

RewriteCond %{SCRIPT_FILENAME} -f [OR]
RewriteCond %{SCRIPT_FILENAME} -d
RewriteRule .* - [L]

RewriteRule ^(.+) index.php/$1 [E=VAR1:$1,QSA,L,PT]
#### EOF SSU

Please help!!!!

I don't know what more i can check to make this awesome contribution work.

Thank you!
