To display your shopkeeper bio in your store(s) you need to select the stores in which you would like your bio displayed. In your shopkeeper bio section there is an option listed on the bottom of the page as "Stores to Display." You can select the stores that you wish to have your bio featured in by clicking on and highlighting the shop ID's that are listed. Once you have, save.
When you're done, return to your storefront and refresh the page, if necessary, to see your changes.
Note: If you are using a CafePress template for your Premium Shop layout, you do not need to check the Show Sidebar option. The sidebar is already in built into the template, and will result in a double sidebar. If you are not using a template, you will want to make sure the Show Sidebar option is selected in the Custom HTML are of your account.
