That's good - thanks.

Is that the mess detector? If so it's keyworded and I'm sure I haven't 
installed it before, whereas I had owncloud running ok before my hard disk 
failure. That failure caused me to rebuild from scratch on its SSD 
replacement, because so many disk-unreadable errors came up at the end that I 
didn't trust anything stored on it.

I've included this stanza in default_vhost.include:

<Directory "/var/www/localhost/htdocs/owncloud">
        Options Indexes FollowSymLinks MultiViews
        AllowOverride All
        Order allow,deny
        allow from all
        Satisfy Any
#       Dav Off
</Directory>

With that # mark omitted I get this:

# /etc/init.d/apache2 start
 * apache2 has detected an error in your setup:
Syntax error on line 70 of /etc/apache2/vhosts.d/default_vhost.include:
Invalid command 'Dav', perhaps misspelled or defined by a module not included 
in the server configuration
 * ERROR: apache2 failed to start

So the WebDAV module is not available, which makes sense because it isn't 
specified in /etc/conf.d/apache2. With the # present I still get the error from 
owncloud. Apache was remerged overnight; PHP has just finished, but reloading 
Apache still gives me the owncloud WebDAV error - so PHP isn't to blame.

Good idea. Thanks again Mick.

I've just found something odd. It looks like Apache is not listing on IPv4, 
only IPv6:

# netstat -tulpen | grep apache
tcp6       0      0 :::80                   :::*                    LISTEN      
0          225562     29055/apache2       
tcp6       0      0 :::443                  :::*                    LISTEN      
0          225558     29055/apache2       

No mention of plain tcp. Eth0 has an IPv4 address, of course, so I have more 
detective work to do.

# ifconfig
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.0.2  netmask 255.255.255.0  broadcast 192.168.0.255
        inet6 fe80::7271:bcff:fe94:ee71  prefixlen 64  scopeid 0x20<link>
