Because this theme isn’t released into the Tumblr Theme Garden and I’m selling it independently, installation is sort of a pain. Unfortunately, there’s no easy way to install it without copying and pasting. Most people run into trouble when opening the file into a program that parses the text as HTML, so you’ll need a basic text editor in order to open the file.
This should work! If it doesn’t, you could temporarily change your password to something simple like “passwordfornatasha” and I could go in and troubleshoot it for you. (I’m very fast.) Just e-mail me if you’re having trouble at info@onebyfourstudio.com.
