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

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

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
