My form has:

Search
Taxonomy: product_cat
Sort Order
Post Per Page
Post Meta: _price
Reset Button
Submit Button

The search seems broken, but that is mostly due to one single reason.

For this explanation I disabled AJAX and use only Submit manual, my settings are as recommended, Woocommerce Shop display results, correct post metas etc. The search I think works good. Let me start saying that the price widget, doesn’t work, at all. It firstly worked when I had 20 products, but then it stopped (not 20 products as in time frame when testing this website, not in correlation), I haven’t changed anything, I only added 30-40 products by duplication, I added more since than with import, but it does not work. I change/slide it, the link changes, I submit it, nothing.

Categories work half the time, and this is mostly because the filter form switches from the default shop archive-page.php to taxonomy-product_cat.php. So when I visit the store the first time, it is on archive-page.php, I use the filter, select category – switches to taxonomy-product_cat.php with the correct results, but when I search again, for example I change my category from the drop-down, it first goes to archive-product.php, resetting my search results, like clicking reset and ignoring what I selected, and if I then just click again on the submit button, it works correctly. Of course this is not an intuitive/nor I think intended way of working.

Last thing is the results per page, when the price filter worked, the result page did not count properly – not that the price slider does not work, I cannot tell.

It would be great to get these stuff resolved, thank you!
