htaccess and 404 From hell!

[eluser]LiorBroshi[/eluser]
This drives me crazy...i've been trying solve this for the past 2 days...
In my site, when i hit refresh on a specific page (article page) everything works fine.
-BUT-
When I try to access the -same- article from my internal search results, it produces the following debug notices on CI's log:

Code:

Where the hell did this 404 came from?
This happens only when I place my .htaccess file which contains:

Code:

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /

    #Checks to see if the user is attempting to access a valid file,
    #such as an image or css document, if this isn't true it sends the
    #request to index.php
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^(.*)$ index.php?/$1 [L]
</IfModule>

Any ideas?

this is the error

Code:

ERROR - 2010-05-25 20:29:19 --&gt; 404 Page Not Found --&gt; 5223 <-- this is the ID of the article, uses show_article/5223

so , from your internal results you get this url :

Code:

show_article/5223

show_article?? is the controller? so what's the function ?? or viceversa???

compare the 2 urls to see if they have the identical segments for the same "search"
