no scroll function in islagrande on mobile divices

Hi @ all
at first I am not a native speaker, so I am sorry for my English ;). During design my website with the free theme islagrande I found out that I could not scroll the website. The index site is ok but not the other (f.E. abou.html).

<section class=“home-slider js-fullheight owl-carousel”>
<div class=“slider-item js-fullheight” style=“background-image:url(images/bg_3.jpg);”>
<div class=“overlay”></div>
<div class=“container”>
<div class=“row slider-text justify-content-center align-items-center”>
<div class=“col-md-7 col-sm-12 text-center ftco-animate”>
<h1 class=“mb-3 mt-2 bread”>About Me</h1>
<p class=“breadcrumbs”><span class=“mr-2”>Home</span> <span>About Me</span></p>

Thanks for your help

hey there

thank you for the question, can you please provide link to the website?
i think this can be fixed by the custom css
