Ok! After looking for ages, I’ve just found the answer on another forum so have posted it and marked the post as resovled.
Go to your theme style.css file and under the responsive section (marked with #14) find this line:
@media (max-width: 800px) {
8 lines below that you will find this:
.sidebar { display: none; }
Change “none” with “inline” (or right, left, bottom) and you will see the sidebar on mobile phones.
