[xwiki-users] error installing xwiki 2.0.1

Hi all, I've installed xwiki 2.0.1 on several systems. I've got the error below on a few of them just opening the wiki for the "Recent Changes" - "Failed to execute macro: velocity". I've solved it for one wiki (solved it by accident) exporting and importing that wiki. The second one is to big to do so. The error rises for a farm wiki and a standard wiki. I am switching back to the 2.0 wiki ".war" using the 2.0.1 ".xar" pages. Kind regards mb This is the < 100KB version of that Mail org.xwiki.rendering.macro.MacroExecutionException: Failed to evaluate Velocity Macro for content [## ## Recent changes. ## ## Optional
