[horde] Horde 4.0.1 (final) - on reinstall lost sidebar and The Content_Tagger class could not be found. Make sure the Content application is installed.

I tried to change my install directory from /var/www/horde_beta to 
/var/www/horde and I ran into trouble as follows:

1.  My sidebar has disappeared and I get the error: "File does not 
exist: /var/www/horde/js/hordetree.js, referer: 
http://192.168.10.35/horde/admin/config/?app=kronolith&action=schema" in 
the apache error log.

2.  I can't update the kronolith database.  I get this error:  "The 
Content_Tagger class could not be found. Make sure the Content 
application is installed."

I tried restarting from scratch by uninstalling all packages, deleting 
database, removing the /var/www/horde_beta and then doing the install 
again.  This did not seem to help.  Any tips / advice would be appreciated.

=======================================================================

SOLVED for me anyway by removing all of the the horde packages and then 
doing these three things and then restarting from scratch:

aptitude purge pear-horde-channel
aptitude purge php-pear
mv /usr/share/php /usr/share/php_old

The above worked for me but all of the above may not be necessary and 
may not work in other situations.  My OS is debian stable squeeze.
