Hello @tomaszwp, thank you so much for your reply. What about all Woocommerce orders that are in database linked with previous meta name? Won’t something happen to them if I delete the old meta value? Is there some way how we can change/correct them?
I figured it out, it was problem in template’s index.php file. We wanted to hide posts with category id 52, so we put <?php query_posts(‘cat=-52’); ?> before while cycle. But thank you very much! ??
At first of all I’ve tried reset the permalinks and nothing changed. Then I turned off and on plugins (one by one) and tried, but it’s still not working.
