Hi @fatimaw,
This issue might have been caused by a conflict with your theme or another plugin that also provides an input method. That’s why you’re seeing this problem. The quantity input for Grouped Product on our demo and test site is still normal. You can kindly check that on our demo site
https://demo.wpclever.net/woosg/product/smart-grouped-product-01/
In order to check if this is an issue triggered by another plugin or from inside our plugin, please follow my below instructions. I need to make sure that our plugin is functional with the basic WooCommerce & theme on your site or not.
– Create a full backup of your site and keep it in a safe place.
– Updates all active plugins on your site to the latest versions, and so do WooCommerce and WordPress.
– Switch the theme on your site to the WPClever theme.
– Deactivate all other plugins, except for WooCommerce & our plugin.
– Check the front-end behavior.
Please follow these steps. If after taking these steps and our plugin is working again, then it’s another plugin or theme on your site that has caused this, you can find that out by deactivating plugins one by one to find the culprit.
If you’re using the Premium version of our plugin, you can kindly contact our developers via the contact page to order a customization service for free. They will checkout purchase information and then conduct the customization service for you.
Best regards.
