Trying to submit a comment I get error code 500 (internal server error) and in the logs I find something like:

[error] [client ...] PHP Fatal error: Call to a member function mainNode() on a non-object in [..]extension/ezcomments/classes/ezcomposthelper.php on line 71.

Standard installation of eZComments (downloaded from http://share.ez.no/blogs/ez/the-base-of-the-community-project-ez-publish-fuji-4.4-released-today.-let-s-launch-the-rocket , as the project page has no download link).

I tried reinstalling eZComments with no effect. I have a standard eZPublish installation with webim and no other non-standard extension installed.

Steps to reproduce

I tried to reproduce this on a virtual machine, but I could not. Really puzzled here, I'll try again on the Server.
