Product Gallery Images Changed with Update

Hi there,

I updated WooCommerce today, but it has changed the way the product gallery is displayed on the product pages. Earlier today, when you went to a product page, you could use the arrows to toggle through the images and they would all be full size. Now, after the update, only the product image is full size and all gallery images are thumbnails. (see here for an example: https://misneach.ca/product/black-with-lavender-leather/)

I want it to go back to the way it was where the product gallery images were full size on the product page.

It doesn’t appear to have affected the Lightbox at all, just the actual product page.

Please help! I can’t seem to do anything that makes it go back to the way it was. I had been intending to launch my website tomorrow, but this is a major setback.

Many thanks for your help,
Angela
