No print on Woocommerce page

[misiekkb]

I have problem with this plugin on Woocommerce single product, because no print, only I get 404. I add to adventure-tours ->templates->tours->single.php and adventure-tours->Woocommerce->single-product.php, but still this same error 404. Only problem there are on single page product, on other page and list products no problem with printing.

How I may fixing this problem? I use template Adventure Tours, site https://www.hamak-tur.pl/ferie-zimowe-2020/
