I've been following the excellent tutorial here: http://doc.silverstripe.org/sapphire/en/tutorials/1-building-a-basic-site which is very clear, but I have a problem.
I've created a new file inside mysite/code and and pasted in the code from the tutorial above. I then flushed my database using the url http://localhost/silverstripe/?flush=1
But when I go back into the admin system (I refreshed the page first), choose a page and go to "behaviours", the page type dropdown doesn't show my new page type.
Is there an additional step that I'm missing?
Thanks
