I haven't seen this one... What version of Plone, and what exactly were you looking at when you got the error? the root of the plone site?
sorry for the late answer. I was away from work... it works now!!!! I have installed plone version 1.0.5 with the default settings on the two machines, after that I added the folder ZSyncer (this time I installed version 0.5.0-pre12 instead of version beta10) to the directory ....plone/Zope/lib/python/Products/ I also used the patch at http://www.dieter.handshake.de/pyprojects/zope/#bct_sec_5.3 to be able to sync plone folders as well I restarted plone and added on the plone root a ZSyncer Object. here (ZSyncer object) I added the name and password of the admin to be able to access the data of the other machine. I also choosed the same types to be synced on both machines. On one machine I set up the destination and started the sync process: worked fine! the rekursive search mode is very usefull for me, since I want to set up a cronjob, that sycronizes the two machines (unfortunately people are adding content on both machines, thats why I have to run the cronjob on both machines). perl script: my plan is to set up the cmd manage_sync via http, get the answer and update the wanted items again via http. Paul, thanks a lot for your great job on Zsyncer. BTW: Paul, when to you plan to release version 0.5 of zsyncer? cheers, david.
