There was an issue with the automatic update for the repository of Skript fixed in #4994 don't know if the website updates based on that, but @AyhamAl-Ali and @Moderocky are handling the website, and would be able to update both the repo and the website.

There wasn't any changes to the documentation as no new syntaxes or syntax changes were done, so it's not a worry for the Skript user.

Currently Skript Documentation website is updated manually, hence the version tag in the header right corner that reflects the current docs of which Skript version generated.

Automatic docs site updating is a WIP

This has been done now that we've moved repositories :)

Let us know if you have any issues with the site!
