How time flies. I was finally able to work a bit on my WordPress themes after 3 years. Made sure they still work with WordPress 6 and has support for up to PHP 8. Just minor changes. On upcoming updates I’m thinking of having the option to host the fonts locally. Font GDPR issue.
Frontier theme is still unavailable on wordpress.org, I don’t know if I’ll ever get it back there in the Theme Repo since a very long time has passed since I last interacted with the Themes Team and I’m now ashamed to show my “face” there 😂😢 but you can download it from the link below.
As for blocks or gutenberg support, I don’t have the know-how nor the motivation get into those. Check this plugin out if you still like working with the classic editor.
These themes are also tested to work with ClassicPress (WordPress alternative).
