View source for Updating mediawiki to 1.19.1

On August 24, 2012 my goal was to have [http://www.mediawiki.org/wiki/Extension:FacebookComments FaceBook Comments] on this page. It did not work with mediawiki 1.16. The page itself states it runs on mediawiki 1.18 so I decided to update to the latest version of mediawiki which was 1.19.1.

= Backup =
First I did a backup

== File system ==
Backup of the file system:
 /srv/www # cp -pr htdocs/ htdocs-backup

= Update mediawiki =
 /srv/www # cp /root/mediawiki-1.19.1.tar.gz .
 /srv/www # tar xvzf mediawiki-1.19.1.tar.gz 
 /srv/www # ls
 cgi-bin  htdig  htdocs  htdocs-backup  mediawiki-1.19.1  mediawiki-1.19.1.tar.gz
 /srv/www # chown wwwrun:www mediawiki-1.19.1
 /srv/www # cp -pr mediawiki-1.19.1/* htdocs

= wgServer problem =
Then I had
 LocalSettings.php:$wgServer           = "http://www.linuxintro.org";
and 
 LocalSettings.php:$wgScriptPath       = "/staerk/thorsten";
As soon as I change to $wgServer to http://www.staerk.de and $wgScriptPath to "/thorsten" the style of the page changes to a very ugly one, just as if the skins were not readable any more.

Seems I had a line in the apache config that made apache redirect strangely:
    Alias /thorsten /srv/www/htdocs/staerk/thorsten/index.php
after uncommenting the thing worked.

= Skin change =
Now after the update the default skin is no longer MonoBook but VectOr.

= Short URL issue =
Before my articles were on http://www.staerk.de/thorsten/article, now I have to do the [https://www.mediawiki.org/wiki/Manual:Short_URL short URL rewrite] again.

After implementing https://www.mediawiki.org/wiki/Manual:Short_URL/Apache the style was lost as described [https://www.mediawiki.org/wiki/Manual:Short_URL#No_Skins here].

Now I have two situations. Either styles work but I cannot access www.staerk.de/thorsten/''article'' or I can access www.staerk.de/thorsten/''article'' but styles do not work. To switch between these two situations I need to do the following changes to LocalSettings.php and /etc/apache2/httpd.conf

The following line in httpd.conf makes the styles get lost:
 RewriteRule ^/?thorsten(/.*)?$ %{DOCUMENT_ROOT}/thorsten/index.php [L]

= Solution =
Solution???
Follow this other tutorial, add ScriptAlias also for /thorsten/skins
NO!
The problem was that load.php now loads the CSS, so you have to except load.php5 from the alias like this:
 Alias /thorsten/load.php5 /srv/www/htdocs/staerk/thorsten/load.php5
