All my components (text, photos, buttons, etc.) disappeared when I changed template
Each template has its own default elements and each element is placed differently per template. So, after changing template, your created website will be lost.

New template is shown or website builder asks to choose template instead of showing my website
1. You accidentally pressed "Reset" or "Change template" button. Check if you have manual or automatic backup enabled. Hover on Publish icon and you will see "Backup/Restore" item;
2. You closed website builder without pressing "Save draft" after creating a website.
Always make sure you saved your website before closing browser tab. Also we advise to make website backup regularly.
