OpenWRT web admin (LUCI) wierdness

I had a router configured with OpenWRT BackFire (10.03) and had a need to upgrade it to support the web management interface.

So to do this login to a console and:

opkg update  
opkg install luci-light luci-theme-openwrtlight 
/etc/init.d/uhttpd enable 
/etc/init.d/uhttpd start

However, in my attempt to streamline things and reduce disk usage I managed to only have the ‘Essentials’ menu, this was missing various important items such as detailed dnsmasq settings (which was the whole point of the exercise.) So I pushed on and installed luci, which should have enabled the “Administration” menu but did not.

After much mucking around and browsing through the installed files, I stumbled upon this:

rm /tmp/luci-indexcache 

after which logging in the “Administration” menu is now present.
