Getting the exact same notice. Did you find any solution?
Hi @dualcube.
Thank you for getting back to me.
I don’t want to remove the tab. I actually want to remove the “More Offer” LINK/BUTTON which on clicking shows the “More Offer” tab.
Here is the screenshot https://www.awesomescreenshot.com/image/3488670/5e6ff646dcaadf21d82cfd223e61fc5c
I did some searching and found out that this LINK/BUTTON is being added to the product summary using the below hook in classes/class-wcmp-product.php file.
add_action('woocommerce_single_product_summary', array($this, 'product_single_product_multivendor_tab_link'), 60);
Thanks.
