Any way to modify the footer?

The footer that says Grav was with by RocketTheme.

Just edit it in the theme. Nothing special going on. I can't tell you exactly how to edit that, because it depends on the theme, and every theme is different.

Hi, thanks for the reply. I'm using the standard Antimatter theme. I've looked through the user/themes/antimatter folder but haven't been able to find where I could modify that.

templates/partials/base.html.twig, line 74.

Hint: you can find things easily by loading the folder in a text editor (Sublime Text for example) and searching a specific word.

make sure you walk through the Basic Tutorial https://learn.getgrav.org/basics/basic-tutorial a few times.
