What's happening to my asciidoc?

[David Demelier]

Hi,

I've been using asciidoc for a while, I've updating it to
asciidoc-8.6.8_1. But now I can't generate any correct documentation.
It does not even add :toc: field.

For instance the following example should generate a HTML with its
popular blue theme :

Test
===
:Author: David
:toc:

= Title

Some data

== Title 2

Some data

For me, it produces a very light HTML file with no table of content
and everything is black, I also notice that it does not append any CSS
code.

Does anyone already have this issue?

Cheers,
