PHP waring on site

Hi,

I recently started translating a site to Hebrew and noticed that the price widget is not appearing at all in RTL version, nothing in the HTML, all other widgets work fine,

I did some research and found there is a php warning (in both english and hebrew) when ever I refresh my Shop page with a price filter in the URL like,
/shop/?filters=price[21.00_180.00]|color[17]

when I just work it with Ajax and no refresh there is no error.

This is the php error, It did a test on a clean theme and no plugins and same

PHP Warning: call_user_func_array() expects parameter 1 to be a valid callback, class ‘WC_Query’ does not have a method ‘price_filter’

Any ideas ??
