Remove Sidebar from Woocommerce Product Page

Hey guys,
A non CSS literate being here.
Recently added Woocommerce to my site for the sale of gift vouchers. Also added YITH Gift Voucher.
I’m trying to fine tune things and cannot for the life of me figure out how to remove the left sidebar from the link provided to my product page.
I’ve tried all options that I could find on the various support forums on WordPress and Woocommerce, but alas nothing has worked.
When I edit the page in question and use the Advanced Layout Builder I receive the ‘product will not work..etc.’ I then switch to the ALB and adjust the sidebar settings and this removes the side bar but nothing then shows up on the page (it’s blank).
Once I select the Default Editor and update the page returns to showing the product but the side bar remains on the left hand side.
I’m not literate in CSS but if required I can learn.

Any and all help is greatly apprecaited,

Ambrose
