No pagination on homepage & child theme slider not working

Hi,

I have the latest theme version installed here: https://laurabucur.ro.
Also, the latest WP version.

I have two issues:

a. The homepage does NOT display the pagination.
Here is what it builds:

<div class="blog_posts_nav">
<div class="prev_posts"></div>
<div class="next_posts"></div>
<div class="clear"></div>
</div>

I am using a page that has the Homepage template selected, and it is set in the Customizer as a Static page for the homepage.
On the Blog page it does show up, so I do not really understand why this is happening.
b. I tried to fix this issue by adding a temporary button to “more posts” – you can see it as a big pink button on the home. But as this is a change to the theme files, I tried adding a Child theme, but if I activate it the Slider will no longer work.

So basically all of my work on your beautiful theme is for nothing, because it is unusable.

Can you please help with this?

Thank you,
Alexandra
