Gonna update to the latest theme release, I forgot I haven't updated in a while.

Edit: The issue persists on the latest release.

[itsmartashub]

Yep, that’s expected. The hardworking Florisboard team introduced a new theme engine (Snygg2) starting with v0.5.0-alpha01, which changes how themes are structured and styled.

Floristyle needs a full rewrite to support it. Every theme has to be reviewed, updated with new elements and properties, and tested.

Hopefully it’ll be ready in the next few days, there’s a lot of themes to migrate 🥲

So for now, the latest supported Florisboard is v0.4.6

[Unbaised99]

Yes there is need of rework on theme for new 0.5 release .

[itsmartashub]

The latest v5.0.0 version should resolve this issue.

Thank you for the updated Themes, I've approved the addons store release so everybody can download it from there.

[milesflavel]

Thank you for the quick update, the new version works great and appears to be way more than just a small fix for the schema change

[SebiTalent04]

Everything works again, thank you for your work!

It's not broken and working as expected. The theme you are trying to install was made for florisboard v0.5.x and thus is not installable on v0.4.x. You can either download the latest release made for FlorisBoard 0.4 or use the latest beta release of FlorisBoard.

@lm41 was faster 😅 Thank you for explaining things clearly and providing the links.
