Next Page Navigation doesn’t work on Home Page

Page Navigation / Pagination doesn’t work on my home page. It works everywhere else on the site works, but not on the index page. Using the WordPress default, a link to Next Page appears on the bottom of the page, when you click on it, it is supposed to bring you to mydomain.com/page2 but instead it just reloads the page. The same happens when I use the WP_PageNavi plug-in.

I have already re-loaded my rewrite rules. And this did not solve the issue.

I have very minimal knowledge of PHP so you’d have to tell me what to write, and where to paste the code. I tried the theme developer but was not able to get any help from them.

Our site is https://www.gadgetmatch.com and our theme is Story from Pexeto.

Thanks in advance.
