Thank you, that help. But i have another issue, when I have Permalink set as a "Plain" my blog site looks different than when I have set permalink as a "Post name". But I think I can try to create another site and set as a Blog, we will see. 

first of all, you need to enable proper permalinks

And I think that this will fix your issue

We are not able to check sites by screenshots. Please, provide link of site
and screenshot how you enabled comparison in theme option

I have a problem with items comparison. I have two product added to comparison but when I want to compare them, there is “No products for comparison”. I saw that site, http://rehubdocs.wpsoul.com/docs/rehub-theme/shop-options-woo-edd/dynamic-quick-comparison/ and I have site with [wpsm_woocharts]. I don’t know why is that not working. Please help. I don't want to provide  a direct link on page yet. If it will be really needed then then I will share you a view of my page.
