@pelliot: The simple option to upgrade the Catch Box Pro from 2.1 to 2.2. Follow the following steps.
1. Activate the Catch Box Free Theme
2. Delete the Catch Box Pro version 2.1
3. Then download the latest version of Catch Box Pro from our site
4. Then install the latest version of Catch Box Pro as the new theme installation.
All your custom menu, header, and changes in Custom CSS and Theme Options will remain as it is. There won’t be any effect.
That is why we don’t recommend users to edit any core theme files such as style.css and fucntions.php which will be reverted when you update any theme.
