I would like to change the theme of my blog but when I preview the new theme, none of my widgets are showing on the new theme. Is that just because of the preview or do I have to recreate the widgets on the new theme separately? Will the widgets, info migrate automatically to the new theme?
When you preview a theme you are seeing a “default sidebar display” that does not contain actual widgets. When you activate a new theme the widgets you previously used will be there.
No content is ever lost when switching themes and it takes only minutes to do this > appearance > Themes > Select theme > click “activate” when the thumbnail image appears. There may be some in the Inactive Widgets box > Appearance > Widgets > Inactive Widgets box that you will need to install in the sidebar or footer areas for widgets. Simply drag and drop them into place, click to open, click “save” and ‘close” and that’s it.
