'Read More' Button Not Showing

Hi !

I had the same problem. Movin already answered this question in this post : https://colorlibsupport.com/t/a-few-questions-how-to-make-only-the-first-post-full-and-regarding-font/

You just have to add this code to Customize > Activello Options > Others > Custom CSS

.read-more {
    display: block !important;
}

Hope this helps !
