The content on your home page is controlled in “Appearance —> Parabola Settings.”
It is strongly recommended that you export your Parabola settings before you change any of the settings in this panel. That way you can import your previously saved settings again if you don’t like your new settings.
The settings for the home page can be found under the “Presentation Page” tab.
You should not change these settings unless you have an understanding of what you are doing. There are FAQs on the theme developer’s website that you can use if you want to familiarize yourself with this panel before changing any settings.
