Filter "remove" button

When i am pressing the reset button on filter, the page forward me to a "Page Not Found ".

The redirection url is http://www.********.com/index.php?dispatch=INDEX_SCRIPT



How can i fix it?



Also i would like to change the colour and the size of fonts of filters.

Which line of style.css i have to edit?

I have the same problem with the admin panel.

When i am trying to log in the frist time i get a message that PAGE NOT FOUND but in the top of the page are the menu of admin panel. So when i am pressing for example “Orders” i can view and edit my orders.
