[Mediawiki-l] PHP warnings in page headers and update.php after updating from 1.8.2 to 1.9.3

[Thomas Boehne]

I updated our Intranet wiki from 1.8.2 to 1.9.3 using the shell based
update.php script. It ran through all the way but printed some
warnings:

[...]
Checking if pagelinks index pl_namespace includes field pl_from...
...index pl_namespace on table pagelinks has no field pl_from; adding
Deleting old default messages..."" is not a valid magic thingie for "special"

Warning: array_slice(): The first argument should be an array in /var/www/mediawiki-1.9.3/languages/Language.php on line 1105
"" is not a valid magic thingie for "defaultsort"

Warning: array_slice(): The first argument should be an array in /var/www/mediawiki-1.9.3/languages/Language.php on line 1105
Done
Purging caches...done.
Done.
linuxsrv1:/var/www/mediawiki-1.9.3/maintenance# cd ..

The Wiki does now run with version 1.9.3, but on every page I get 3
warnings in the header:

Warning: array_slice() [function.array-slice]: The first argument should be an array in /var/www/mediawiki-1.9.3/languages/Language.php on line 1105
Warning: array_slice() [function.array-slice]: The first argument should be an array in /var/www/mediawiki-1.9.3/languages/Language.php on line 1105
Warning: Invalid argument supplied for foreach() in /var/www/mediawiki-1.9.3/includes/SpecialPage.php on line 199

As a temporary workaround, I set error_reporting(0) around those
lines, but that's obviously not a proper solution.

There seem to be other users with the same problem, but I did not find
a solution anywhere on the net. Why do these messages occur and how do
I fix this? This error can also be observed on
http://www.apple2games.com/wiki/Main_Page

I reported the error on
http://www.mediawiki.org/wiki/Project:Support_desk#PHP_warnings_in_page_headers_and_update.php_after_updating_from_1.8.2_to_1.9.3
but did not have any responses so far.

Any ideas?

Best regards
