Using Pharo 8.0 64-bit, I ran this from the TinyBlog book:

Metacello new baseline:'TinyBlog';

repository: 'github://LucFabresse/TinyBlog/src';

onConflict: [ :ex | ex useLoaded ];

load.

When I load the page and login as ‘admin’ and password, the page displays:

Seaside Walkback

SubscriptOutOfBounds: 1

Debug Full Stack

Why is that, and what is the correction fir it? Thanks

Clicking on debug, it return in Pharo:
