white page after filter applied

after filter products are applied i get blank page e.g BRANDS.
P.S if theme update is required,how do i update it please?i do not see any dashboard message for theme update,even if i have recieved an email with update message.
Thank you

after theme update it is ok but one question please:
if you visit https://kourtakis-lighting.gr/product-category/fotistika-esoterikou-xorou/anemistires-orofis-fotistika/ and you apply the taxonomy shorten from low price to expensive then from default https://i.imgur.com/c36sjeP.png you see the product view again normal https://i.imgur.com/bghLIMM.png.
if you go to another product category https://kourtakis-lighting.gr/product-category/fotistika-esoterikou-xorou/aplikes-toixou/ you will again see the view as normal https://i.imgur.com/8GvVrxR.png BUT HERE if you apply the taxonomy shorten from low price to expensive then from default you see the product view in another view https://i.imgur.com/sHebhU1.png.
How can i apply it please to show the same to all the product categories taxonomies?
thank you
