Looks like a BUG with New 8.6.1 Version of WooCommerce

Hi @azpub,

Could you kindly add this custom CSS to your site (Appearance > Customize > Additional CSS)? After adding the CSS, could you check if it solves your issue?

.woocommerce div.product .woocommerce-tabs .panel {
	background-color: #e2e2e2 !important;
}

Please note that this is not a bug. The theme you are using is probably not fully compatible with WC 8.6.1.

I hope this helps! If you have any other questions, feel free to ask.

Hello Shameem, OK Thank, you the issue is FIXED now. Thanks for the fast feedback
