Hi
I use from this code and work correctly. but show a Notice in top of the every product in single page. That Notice is:
"Notice: Trying to get property 'term_id' of non-object in /home/micromod/domains/micmodshop.ir/public_html/wp-content/themes/avada-child/functions.php on line 155"
How can i fixed it?
