"This page is currently offline." (I seem to have the good PHP version)

The CMS Questions

I am starting to work on a new Kirby website.
I’ve just downloaded the most recent version of the Plainkit directly from the Kirby website.
I’m using MAMP (PHP version 7.3.8)
On my localhost, I get this error message:

"This page is currently offline. We are very sorry for the inconvenience and will fix it as soon as possible.

Advice for developers and administrators:
Change the PHP version to one supported by your version of Kirby"

Do you know what I should do?
Thanks

The latest versions of Kirby (3.8+) only support PHP 8.0 and 8.1, so your installed version is too old.

Oh ok! Thanks! Will try to make the switch
