[Mediawiki-l] Questions: Escape syntax for html and error in Allmessages

[Mailing HEAVY.ch]

hi there

i'm new to mediawiki and i've come around to ask you guys some questions.

1. escape syntax for html
========================
I would like to integrate an button(link) as an image (like a main site
with graphical navigations buttons). The REDIRCT link doesnt' works for
me 'coz it shows always the graphic (button) on the top of the
redirected site (normaly i agree i great function). So I told about a
escape sequenz, that I can integrat <a> and <img> tags. is this exist?
just to edition the parse.php file and to remove the check for "not
allowed" html-tags wouldn't help 'coz I just want to use this function
on some mainsites.. normal-user should not be aviable to integrate such
html-tags.


2. Spezial:Allmessages
========================
I installed the MediaWiki: 1.5beta4, # PHP: 5.0.3 (cgi), # MySQL:
4.1.10a and recive the following errormessage if I call the:
http://news.heavy.ch/index.php?title=Spezial:Allmessages

everything else seems to work fine.

-- Logmessage --
Warning: array_merge() [function.array-merge.html]: Argument #2 is not
an array in

Warning: Invalid argument supplied for foreach() in
/home/heavych/public_html/news/includes/SpecialAllmessages.php on line 36
-- END Logmessage --

So is this a bug in the mediawiki or it has to do with some data that
maybe I included in some fields?

thx for any replies.
