Sometimes when you move a lot around in DokuWiki, maybe because you changed your layout or went with a new page structure it can be useful to clear everything cache wise in Dokuwiki and reindex the whole thing - This is also true if moving your wiki from one host to another.

For this exercise we will assume that your DokuWiki resides in /var/www/html/dokuwiki

cd /var/www/html/dokuwiki/data
sudo rm -rf cache/*
sudo rm -rf meta/*
sudo rm -rf media_meta/*
sudo rm -rf index/*

Do not delete the directories themselves, only their contents.

Optional but recomended - Rebuild the search index

cd /var/www/html/dokuwiki
sudo -u www-data php bin/indexer.php rebuild
<code>

You will see something like the output below.
<code>
Searching pages... 185 pages found.
namespace:page... Indexer: finished
done.

Check that /data/index/ now contains freshly timestamped .idx files.

ls -lh /var/www/html/dokuwiki/data/index/
