Include CSS... i'm lost

[eluser]Hana[/eluser]
Ok then... I understand now why I had this problem...
I'll move my "assets" to root out of Application Folder :-) thanks for the tips!

So I moved assets folder back to root.
Then I modified again my .htacces in root:
RewriteCond $1 !^(index\.php|assets|robots\.txt)
To finish, I put back the .htaccess with Deny from all in my folder Application (& System).

Everything is secure & works! Great and thank you :-)
