Content in Sidebar Is Lost
If your old theme had some custom areas in Appearance > Widgets, you may lose them when switching to the Jupiter theme. The reason is that Jupiter is designed differently and has its own widget areas.
To get the content in your sidebars back, you’ll need to add the widgets again to the new Widget Areas.
If you use some sort of analytics tool, whether it be Google Analytics or another service, and you added the tracking code to the footer.php file instead of to a plugin, you will lose the code once you migrate to the Jupiter theme. So, you’ll need to make sure that you copy and paste your tracking code into your new theme. This is one of the things that is very commonly overlooked by users.
Fix Thumbnail Sizes
It may happen that all of the new images that are uploaded after activating the new theme look good, but the old thumbnails appear ugly and distorted.
When you upload an image to WordPress, it creates duplicate images of the original in different sizes and saves them in the uploads folder. WordPress gets the thumbnail image size information from your theme. Your theme defines the thumbnail sizes, which are really useful in order to load the best image size when needed. These new image sizes are only applied to the images that you upload after activating the new theme.
To solve this problem you’ll need to generate new sizes for all the previously uploaded images. This process is often referred to as regenerating thumbnails and there is a plugin to help – Regenerate Thumbnails.
