La cache del mediawiki m'ha donat males passades.

Com deshabilitar-la, ja sigui per sempre, o de forma instantània, està explicat a la FAQ: http://meta.wikimedia.org/wiki/MediaWiki_FAQ#How_do_I_completely_disable_caching.3F

==How do I completely disable caching?==

Add in your LocalSettings.php file the following lines:
<pre>
$wgEnableParserCache = false;
$wgCachePages = false;
</pre>

Nota: la cache m'ha donat molts problemes quan alterno entre http://wiki.empresalibre.org i http://localhost/wiki. Aquesta és la solució que he trobat.

==How do I purge cached pages?==

*You can use ?action=purge on individual pages to update their cache dates.
*There is a global $wgCacheEpoch variable which can be set in LocalSettings.php to invalidate all prior cache entries (see DefaultSettings.php)
*If you want to purge all pages in the parser cache, truncate objectcache table from the wiki database. You may use this command:
<pre>
TRUNCATE TABLE objectcache;
</pre>
*A shell script such as this may be used
<pre>
#! /bin/bash
# mwpurgecache - invalidate mediawiki cache

set -e

PROG=$(basename $0)
VER=0.1

function version() {
echo "$PROG $VER - invalidate mediawiki cache

function usage() {

echo "Syntax: $PROG [options] [--] [pages]

Options:

-H, --host host name (default: localhost)
-w, --wiki WIKI server path to wiki (default: /wiki/)
-u, --user USER username for HTTP authentication
-p, --passwd PASS password for HTTP authentication
-d, --dryrun show commands without executing them
-q, --quiet quiet (no output)
-v, --verbose be verbose (print server response)
-h, --help display this message
-V, --version display version information

Options and arguments must be separated by whitespace. WIKI must
match wgArticlePath, such that \$wgArticlePath = \"WIKI/\$1\". WIKI
must not contain regex special characters.

This script requests all wiki pages listed on the command line by
HTTP, prefixed by the wiki path, appending \`?action=purge' to the
URL. If no pages are specified, it retrieves the list of all pages
from Special:Allpages.

Examples:

\$ $PROG Main_page Help:Contents
\$ $PROG -H wiki.my.org -w /mediawiki -u joe -p banana
\$ $PROG -H wiki.my.org --dryrun | wc -l
