[Mediawiki-l] Page rendering on mediawiki 1.6.x

Sun Apr 30 23:28:31 UTC 2006

L.S.,

I'm using mediawiki 1.6.3 and I've hooked in an RSS feed on page level.
However, the feed icon (firefox) only shows when I do something with the
page: Edit it e.g.

Does anyone know how can I change this behaviour?

Thanks in advance for your answers,

Hans Oesterholt-Dijkema
