Hi,
For credentials, the best is to use our "contact us" form with a link to that forum thread.
www.hikashop.com/support/contact-us.html
To hide the filters on the listing, you can use CSS to hide them or you can use a view override to not display them.
Regards,

By the way, do not send me private message, use the "contact us" form instead.
