We need help with these issues.
- Fix login on home page so that it allows users to login AND register (right now it just allows registrations)
- Easy Blogging plugin does not display standard navigation options when logged in as a subscriber/user (for example: users can not see products tab). When plugin is deactivated, all tabs are then displayed.
- How can we set up a universal theme(for shop owners) so they do not have to activate one when they sign up.
- Unclear as to why we have multiple “shop templates” under “My Sites”. We would like One site and a main template for new shop owners to use.
- How do we control the widgets (or standard information) that users see when they first login to the dashboard (for example: shop stats / new orders / etc). We would like to delete existing wordpress widgets such as: At a Glance, Wordpress News, Quick Draft, Activity, Comments.
