Can’t add product images to WooCommerce products

I’m simply trying to upload a product image for each product on the “Edit Product” page . However, i no longer get the upload image popup. it now sends me to the link above but I cant choose any of the images I have uploaded. or when i try “product gallery” it sends me to the top of the” add new product” page. How do I get the product image upload area to show up in WordPress?

I have tried changing my themes but I still get the same problem.

The page I need help with: [log in to see the link]
