When you download the Celestial Reloaded theme, it’s a package file. Unzip that to your desktop because inside is another zip file, which is the theme you install. However, I’m working on the next update of this theme which is going to be version 2.6.6, which is why I want you to contact me from the Email Support form and I will send you the updated version. But still download the version 2.6.5 package because it has updates of a child theme, custom style for the slideshow…and more. But the theme I will send you can be installed to replace the old one you have.
