Note: There is no risk of losing your settings and pages when you update the theme. However, any modifications you have made to the core theme files will be lost, so you should back up those files before you update the theme.
Tip: Make sure your unzipping software does not create any extra directory with the same name nested within the BeTop\ folder.
Final Tip: Whichever method you use to update your theme, clear your browser cache after each update if you notice anything off. Old theme files can sometimes persist in your local cache and make you think something’s wrong.
