Question: Help! Everything on my page disappeared when I selected a new Theme or Package!
It sounds like you may have applied a new "package" or “theme” to your site after having already added custom image and text content to your site. When a new theme or package is selected, widgets have nowhere to go and are wiped out. Essentially, it's like pulling the rug out from under your widgets - they have no where to go.
This is why it is important to back up your website content on your computer, via a word processing document of some kind. This way, you can easily rebuild your site if you accidentally change to a different theme or package, or decide to go with a different look and feel for your site in the future.
