Mercurial: Error - abort: operation not supported over http

[Andreas Schott]

Hello

I installes Mercurial on my Server. Local at the Server everything works 
fine (editing, hg status, hg diff, hg log, hg commit).

hg --version
Mercurial Distributed SCM (version 0.7)

Is it too old? Should i install the 0.9.5?

I can see the Repository over the web too and i see the changelog, after 
i changes files on the server.

Afterwards i pulled the Repo to my PC at home. After editing a file an 
commit i tried to sync the repo at the server by

hg push  http://ip_of_server/hg/
pushing to http://ip_of_server/hg/
abort: operation not supported over http

The hgrc at .hg-Dir contains

[web]
description = easyPortal
author = Andy (Sinai) <xxx at xxx.de>
allow_archive = gz bz2
push_ssl = false
allow_push = *

[web]
style = gitweb

So i don't understand what went wrong?

Can you help me?

Sorry for my bad english
