There's probably a better solution but i did it this way (i presume you know how to use some FTP program).
- In your theme folder, create a "woocommerce" folder, and then inside of it, create "loop" folder
- Then in "loop" folder copy "add_to_cart.php" file from "woocommerce/templates/loop"
- Open "add_to_cart.php" that you copied and go to line 55 that starts with
echo apply_filters( 'woocommerce_loop_add_to_cart_link', sprintf( <....
- delete the entire line (don't delete anything after that line)
That way you can remove the "Add to cart" button or you can add instead of it (like i did) something like:
echo '<a href="'.get_permalink( $product->id ).'" rel="nofollow" class=" button">Read more</a>';
which is just a link to the product.
Like i said, there's probably a better way to do it with "functions.php" but i did this way.
