The next step in reviving my wiki was to make it accesible on my iPhone. A quick trip through Google, and I found an answer on Stack Overflow. I installed the extension and the skin, and it worked – for the most part. It did format the content nicely, but I saw the following error at the top of the page.
I haven’t done much with MediaWiki skins, but was hoping it wouldn’t be too hard to fix. So I searched my MediaWiki skins directory for the problematic function, and the following lines stood out:
$ grep -ir initPage skins
skins/Vector.php: public function initPage( OutputPage $out ) {
skins/Vector.php: parent::initPage( $out );
skins/WPtouch.php: function initPage( &$out ) {
skins/WPtouch.php: SkinTemplate::initPage( $out );
I changed WPtouch.php to make it consistent with Vector.php, and the error went away. Following is a diff of the before (top) & after:
21,22c21,22
< function initPage( &$out ) {
< SkinTemplate::initPage( $out );
---
> public function initPage( OutputPage $out ) {
> parent::initPage( $out );
I also changed the Display_Actions flag, to enable mobile edits (among other things). It worked, but the Portrait mode needs a little tweaking:
Portrait: 
Landscape: 
It’s not pretty, but it seems to work fine in landscape mode, so I’ll leave it alone for now. If you’re on a mobile device, you can see it here: datguy.net/wiki
EDIT: I thought that there might be a newer version of the skin. The Stack Overflow answer links to a 2010 page, but the mediawiki gallery links to a 2012 update. I examined the download links and they seem to be the same.
Also, after posting my solution I got a reply from someone that had the same problem, and his solution to the “Actions” problem in portrait mode was to change the “Personal tools” text. I changed mine to “My tools” (in ./languages/messages/MessagesEn.php), and that was enough to prevent Actions from wrapping onto the second line.
EDIT: In the years since I posted this, I have reinstalled MediaWiki without reapplying the changes above.
