Customizable The Error Messages
Custom validation message is not working: ⤵
You have full control over the messages shown to users when they don’t comply with your rules, including:
✔️ Error messages on WooCommerce single product pages.
✔️ Notifications on the WooCommerce cart page/Rules setup.
✔️ Alerts for “Add to Cart” actions in WooCommerce.
You have to use a hook for Custom Validation Message. 🎉
add_filter('wcmmq_custom_validation_msg', '__return_true');
You can use this filter on your site’s Child Theme functions.php or any snippet plugin to add this filter hook.
👉 Now, you can customize the error message or put the translated message in this box: ⤵

Result: ⤵
✔️ We have set it as min quantity 5 and entered the validation message in French Language and it works properly here: ⤵
