<b>Background of the issue: </b>
I am trying to have my product category pages work correctly in both Greek and English on my website. Here is the Loom video for reference: hidden link. Link to a page where the issue can be seen: hidden link
<b>Symptoms: </b>
When I open the product category page in Greek, it usually works fine, but sometimes it redirects to a 404 error page. For English, most of the category pages often go to a 404 page. If I refresh the permalinks, the pages open correctly, but only once.
<b>Questions: </b>
Why do my product category pages sometimes redirect to a 404 error page?
Why do I need to refresh permalinks to access the pages correctly?
