The search by SKU is not working. I have selected in the Theme/general/Search
I have cleared all the cache and still not working. I deactivated plugins and still did not work. Returns phrase “no products” but does work when search a word
Please, confirm the permission for plugins deactivation, and switching to the parent/default theme. As soon as we complete the testing we will enable it all back, You would better make the full backup of your site.
