Default blueprint keeps being loaded

New to Kirby, I’m following along with the video’s. Trying to create my first panel alteration.
Very simple, just create a new blueprint page for “lessen”… but the default blueprint keeps being loaded…
Cleared the ache, double-checked filenames, indentation etc…
Must be something I’m totally missing…

My ultra simple blueprint file contains only a title.

my dir listing below

Anybody Ideas?
I’m on local mamp pro with Kirby 4

Thanks in advance!

What is the content file inside the lesson folder called, it must be lessen.txt in order to picked up the right blueprint.

Hi Sonja,

Thanks for the quick response. Indeed this was the issue.
I’ll continue my Kirby-journey…

Thanks again
