Old URLs still in the parser cache can be cleared by:

to clear the objectcache table in MySQL.
Note that the browser cache may still contain bogus data. You can use
?action=purge on indidivual pages to update their cache dates. Also
there is a global $wgCacheEpoch variable which can be set in
LocalSettings.php to invalidate all prior cache entries (see
DefaultSettings.php).
I had the same problem as the OP, and setting wgCacheEpoch did not
seem to work for me (or maybe its effect was only delayed, due to some
timezone issue...). As my wiki is quite small, I wrote a script to
request all wiki pages with ?action=purge.
In a nutshell, the following commands should do the trick:
host=http://wiki.my.org
wiki=/wiki/
wget -qO- "${host}${wiki}Special:Allpages" |
sed -re '/start content/,/end content/p' -e
's/href="([^"]+)"/\nGREPME:\1\n/g' |
sed -nre 's/^GREPME:(.*)$/\1/p' |
grep "^${wiki}" |
while read page
do
wget -O/dev/null "${host}${page}?action=purge"
done
Here is the complete script, with some boilerplate command line
processing.
#! /bin/bash
# mwpurgecache - invalidate mediawiki cache
set -e
PROG=$(basename $0)
VER=0.1
function version() {
echo "$PROG $VER - invalidate mediawiki cache

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
