Hi,
I enabled the “Disable Right mouse click on images” and it is working beautifully on all pages except the single product page. As soon as the page is loaded, if the person goes directly to the large image of the product displayed and right clicks the image, right click shows the entire context menu. However, if you go lower on the page and try and right click images of ‘related products’ the right click won’t work as expected. Now if you go back to the original large image of the product and right click, it won’t work as expected.
So it seems as if you need to first right-click on other images shown on page to make the option work properly on the large product image shown.
I am using wordpress 4.9.5 and Addison Bold Theme.
