Hallo ikiwiki-team!

I would like to setup ikwiki with AsciiDoc. So far I was able to install the asciidoc.pm plugin and got it to run. However when saving a page of Page type Asciidoc I encounter the error:

asciidoc: ERROR: unsafe: ifeval invalid asciidoc: FAILED: ifeval invalid safe document

This also happens when I afterwards open that page with asciidoc markup. It seems to me that this is a rendering problem!?

Installed on Debian Jessie with ikiwiki version 3.20141016.4

What can I do to make it work?
