Wikimedia Bugzilla is closed!

When I call a page from the Wiki with http://www/wiki/index.php it does not work
(Webbrowser gives me a timeout). If I call it with
http://www/wiki/index.php/Main_Page it works.
After that browsing the Wiki works. If I edit a page and press the 'save' button
I get a timeout (but the content of the page is saved).

Manually calling the wiki from the command line (php index.php) gives no output
at all.

If I insert the line

print_r($wgOut); 

just before $wgOut->output(); I get the ouztput given below.

If I leave the command in the code and browse the Wiki it looks like all the
pages that work have in common, that the mRedirect-field is empty.

The output:
