Hi there,

I installed mediawiki 1.17 and this extension:

Then I get the messages:

Warning: in_array() [function.in-array]: Wrong datatype for second
argument in
on line 317

Warning: Cannot modify header information - headers already sent by
(output started at
/var/www/web468/html/psych-med.de/wiki/LocalSettings.php:1) in
/var/www/web468/html/psych-med.de/wiki/includes/WebResponse.php on line 22

The first message I get also when I install the Cite-Extension.

I tried the bugfix from

but that didn't change anything.

Any idea what's wrong?
