SHow load more reviews

Hi, i have used the shortcode to embed the reviews on my product template:
[wc_photo_reviews_shortcode
comments_per_page=”10″
cols=”5″
cols_mobile=”1″
use_single_product=”on”
order=”desc” orderby=”comment_date”
show_product=”on”
filter=”off”
pagination=”off”
pagination_ajax=”” pagination_pre=”” pagination_next=””
loadmore_button=”on”
ratings=”4,5″
mobile=”on”
style=”masonry” masonry_popup=”review”
enable_box_shadow=”on”
full_screen_mobile=”on”
image_popup=”below_thumb”]

But i don’t see the load more button.

Here is the page:

Besides that, it would be awesome if we can change the error messages of the review form: right now it is in english and my users don’t speak that language.
(i can probably workaround it with Loco translate, but it will be way better to have it in the plugin.

Also, the documentation don’t tell you the default values of the attributes of the shortcodes. It is necessary to know. I had to test each attribute myself.
