Comment: Fatal error during installation

This happens when some scripts are duplicated under the YACS installation tree. This is because the setup assistant loads every script of some kind. If two of them are defining the same class, because they have been duplicated, there is a collision and PHP just dies.

Please ensure that the YACS installation only contains fresh scripts, with no copy from a previous version, etc.

Many thanks for your interest in YACS, and let us know how it goes.
