Scrollbar missing

Hello,
I have several WordPress sites using different themes. I noticed yesterday that the two websites using areview theme don’t have the vertical scrollbar on the right side. I was browsing on a laptop using Explorer and Firefox. With both browsers scrollbar is missing. Is it normal? It 's not really user-friendly…
Thanks.

Hello @poter,

There should be a scrollbar, but it has some opacity (it becomes a little bit brighter when you scroll).

Can you please check it out again and let me know the result?

Kind Regards, Roman.

Hello @Roman,
Thank you to confirm me that there should be a scrollbar.
My site is jeux-bitcoin.com , can you see the scrollbar? I checked it out but it’s not showing up from my laptop.
Regards.

edit: I can see now the scrollbar.

Hello @poter,

You can try to make it more noticeable by using the following CSS code to make the scrollbar white.

You can add CSS code to your site with Simple Custom CSS plugin (just copy CSS code and paste it in Dashboard → Appearance → Custom CSS after installing and activating the plugin). Also you can add CSS code directly to style.css file of your child theme.

#ascrail2000 div {
    background-color: white !important;
}

Kind Regards, Roman.
