I downloaded and installed: Replace tab patch (http://www.zope.org/Members/cguardia/replace) This crashed my Zope when I restarted it on NT Zope 2.2.2 Here is the Traceback for start.bat Traceback (innermost last): File "C:\Program Files\Zopesite\z2.py", line 554, in ? exec "import "+MODULE in {} File "<string>", line 1, in ? File "C:\PROGRA~1\Zopesite\lib\python\Zope\__init__.py", line 95, in ? import Globals, OFS.Application, sys File "C:\PROGRA~1\Zopesite\lib\python\OFS\Application.py", line 91, in ? import Globals,Folder,os,sys,App.Product, App.ProductRegistry, misc_ File "C:\PROGRA~1\Zopesite\lib\python\OFS\Folder.py", line 100, in ? from ReplaceSupport import ReplaceSupport File "C:\PROGRA~1\Zopesite\lib\python\OFS\ReplaceSupport.py", line 93, in ? from DocumentTemplate.DT_Util import InstanceDict, TemplateDict, cDocument ImportError: cannot import name cDocument I modified Folder.py so that there now is nothing about Replace or ReplaceSupport. And that made it working again. You scared me.
