Hello There,
Thanks for writing in! With Icon stack’s unique layout, there may be times where you wish to show a sidebar on your blank templates. If that is the case, select “Yes” to activate your sidebar. You can eliminate the side by deactivating “Blank Template Sidebar” option which can be found by editing your page. Just look for the Icon Page Settings.
For more information, please scroll down at the bottom of this page: https://community.theme.co/kb/meta-options-pages/
Hope this helps.
