I have upgraded from 1.7 and also did a clean upgrade in another server just to check whether it was caused by failure in
upgrade. You can check it out on my homepage: http://www.ironarms.org/~hwasungmars/mediawiki/index.php/Main_Page
You can mess around as you want. I found that other people are having the same problems check out here, too: http://

The problem is that the link does not work, I have to put in "Special" manually to get into the special page. I found out
manual input makes it work fine. The error message says "There is currently no text in this page, you can search for this
page title in other pages or edit this page." And I did a clean install. I do not use ANY extensions.

Relevant information needs to be on this bug report, not accessible via some
third-party URL. For outsiders, the bug seems to be that links to special pages
are missing the namespace prefix, thus causing them to fail. This prevents users
logging in, etc.

In addition, manually entering a special page name, e.g. "Special:Version" in
the search box and hitting Go screws up.

Assuming OS is Linux and the web server in use seems to be Apache. What version
of PHP?

Mediawiki: 1.8.2

Special pages drop the prefix "Special" so that causes them to fail.

Details and comments:
I have tried a fresh install that also resulted in this failure.

Upgrade to PHP 5.1 or 5.2, this is a bug in PHP on 64-bit systems that was fixed a year ago.
