Press Release Script problem!

[TinyShare]

After I installed Pressrelease script , it work very well with admin panel, but when I click on the link to open press release article, I get a white page. I think this is a problem with .htaccess file.
Any one used this script or have the exp with the rewrite mode, please help me, thank !

Here is the .htaccess file :

Code:

###
# (c) http://scriptoffice.com and http://pressreleasescript.com/

#  All rights reserved.
###

Options +FollowSymLinks
Options +Indexes


<IfModule mod_rewrite.c>
RewriteEngine On
#RewriteBase /

# going to install folder
RewriteCond %{REQUEST_URI} (.*)/install/?$

RewriteRule ^(.*)$ %1/install/index.php [NE,R,L]

# going to Admin folder
RewriteCond %{REQUEST_URI} (.*)/admin/?$
RewriteRule ^(.*)$ %1/yad-admin/index.php [NE,R,L]

# working with client side
RewriteRule ^(.*)/$ index.php?qstr=$1 [L]

RewriteRule ^(.*).htm$ index.php?qstr=$1 [L]
</IfModule>

I have installed it in my test domain successfully, it is working correctly. You have to remove commentout before #RewriteBase / like this RewriteBase / if you install main domain or installed in directory like this RewriteBase /directory/
