Re: [xwiki-users] error installing xwiki 2.0.1

Hi all, Just a note: This mail is "for information only", I'll do the next test on that issue running the 2.0.2 version. Thanks mb -----Original Message----- From: users-bounces(a)xwiki.org [mailto:users-bounces@xwiki.org] On Behalf Of Michael Beetz Sent: Tuesday, October 20, 2009 10:15 PM To: XWiki Users Subject: [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
