[opencms-dev] Comments module:

Thanks for your help

Since I am on a production environment I couldnt install OC fresh, but I
did so on my developing machine (Ubuntu 8.1, production is running on
XP). I am encountering the same error there. I will continue to resolve
this problem and if I find a solution posts it here. The only idea I
have right now is to use the module in my template rather than in my
site directly.

>> Ok, not quite sure then. We have been running this module in testing couple of weeks not with no problems. One further idea, are you testing your module within a subsite scope (so your comments properly is not set to /sites/default/comments.xml but /comments.xml), since that might make a difference?
