Most likely cause is that your site is running out of memory. Other than that is a PHP error. So first check your memory by going to WC settings system status and see if you have atleast the recommended memory limit.

If you’re ok there, then I would suggest you looked into your PHP error logs to see what failed.

@bloohair – what you’re seeing is a compressed version of the CSS. Nothing wrong with that. If you want to see the “human readable” version, look for the LESS files. Those files contain the uncompressed CSS code.

WC has ajax add to cart. Did you turn that on?

No it won’t…

You would need to modify product-image.php file template. Copy it to your themes woocommerce/single-product/ folder.

On line 37 is where you want to start editing. Replace the entire line on 37 with something like this (un-tested).

// do this if product is in specific category
if ( has_term( 'my_cat', 'product_cat', $post->ID ) ) {
     echo apply_filters( 'woocommerce_single_product_image_html', sprintf( '<img src="%s" alt="Placeholder" />', get_template_directory_uri() . '/images/my_product_placeholder.jpg' ), $post->ID );
} else {
     echo apply_filters( 'woocommerce_single_product_image_html', sprintf( '<img src="%s" alt="Placeholder" />', woocommerce_placeholder_img_src() ), $post->ID );
}

You can change “my_cat” to the slug name of the category you want OR even the cat ID. Also change the image path to your liking above.

Hmmm I just tested it on my end resaving some of the attributes and I am not seeing any issues.

Were any of your products imported?

You won’t get much response here if the payment gateway you’re using is not apart of WC. If it is developed by a 3rd party, you need to contact them for assistance.

Did you make sure each and every variation has a price set for it?
