no it doesn’t work, no difference. I just can’t set taxonomy terms to posts via Metabox custom fields. Without using Metabox I can set them. Where do I need to put this code exactly? I pasted it into my theme’s functions.php file and also tried Code Snippets plugin. It didnt make any difference. Since I’m not a coder I need some help in understanding your code. What “location” in your code means? “Taxonomy_2” is the name of a custom taxonomy field?
