When you Purchase/Download Theme’s .zip file, first thing you’re gonna do is to extract files from .zip file.
Within extracted folder, there are one file and one folder that are important in order to install your Theme correctly:
File is: your-theme-name.xml | folder is: “upload”
- First upload a content of “upload” folder to the root of your MyBB installation (where “admin” folder is).
- Second go to: Home » Themes » Import a Theme … choose .XML Theme’s file and click “Import Theme” button.
