Hi Linda
If you’re using the Own Store theme, then follow the steps below
Step 1) Go to Appearance -> Widgets
Step 2) Find Topbar Sidebar on the right, open it and edit your content
If you’re using the Own Shop theme, then Go to Appearance -> Menus and then select the Top Bar Menu first from the dropdown ( Select a menu to edit:) and then edit from there
Let us know if this works for you
Best Regards
