Clear cache
Sometimes you need to clear the cache to see the changes ; especially the UI changes (favicon, CSS, logo, ...)
Use the &action=purge command.
ex: http://www.daxiongmao.eu/wiki/index.php?title=Main_Page&action=purge

Favicon
1. Copy your FavIcon to the root of your website. It must be either 16x16 or 32x32 in ICO format.
2. Set 'favicon.ico' rights to 644
3. Adjust your localSettings.php
## FAVICON in PNG
$wgFavicon = "$wgScriptPath/favicon.ico";

Just edit MediaWiki:Sidebar
Source: http://www.mediawiki.org/wiki/Manual_talk:Interface/Sidebar
Ex: http://www.daxiongmao.eu/wiki/index.php?title=MediaWiki:Sidebar
Copyright note
To adjust the text edit MediaWiki:Copyright
To configure the copyrights, adjust your LocalSettings.php
Source: http://www.mediawiki.org/wiki/Manual:$wgRightsText
$wgRightsPage = ""; # Set to the title of a wiki page that describes your license/copyright
$wgRightsUrl = "http://creativecommons.org/licenses/by-sa/3.0/";
$wgRightsText = "Creative Commons Attribution Share Alike";
$wgRightsIcon = "$wgScript/wiki/skins/common/images/creative_commons.png";
Image
Image upload configuration
To enable image upload you need to adjust your LocalSettings.php:
## To enable image uploads, make sure the 'images' directory
## is writable, then set this to true:
$wgEnableUploads = true;
$wgUseImageMagick = false;
$wgImageMagickConvertCommand = "/usr/bin/convert";
#$wgImageMagickTempDir="{$wgUploadDirectory}/temp";
## If you want to use image uploads under safe mode,
## create the directories images/archive, images/thumb and
## images/temp, and make them all writable. Then uncomment
## this, if it's not already uncommented:
#$wgHashedUploadDirectory = false;
#$wgTmpDirectory = "{$wgUploadDirectory}/temp";
You just have to:
- Enable uploads
- Not use ImageMagick
On previous version of MediaWiki I was able to use image magick. However it seems it doesn't work anymore on OVH shared hosting... :( Instead I now rely on PHP scripts.
Insert images
Great tutorial: How to insert images into a wiki article ? See: http://www.inmotionhosting.com/support/edu/mediawiki/adding-content-mediawiki/insert-images-wiki
