@craigh reports here zikula/core#3030 that it upgrades, but installation on a new site fails. Here's the stack trace:

This module version is not yet compatible with Zikula 1.4.6. Do you still have the compatibility? I would be interested in the functions of the module on the live website with Zikula.

Thanks in advance.
