Thanks for quick response!
I only forgot to mention in first post that printers are in fact regular woocommerce tags.
So every product has list of tags that are presenting printers.
I have followed your instructions from knowledgebase without results. It keep showing me the same 4 products that does not have that printer (tags) in there’s list. I tried all possible options without good results. I made another search form just to check if with first one is something wrong. And on the other is the same issue. 🙁
I cannot figure out the solution :/
Sorry to bother you. I really tried everything before contact you and take your precios time…
