Upgrading to concrete18.104.22.168
First, I tried the Dashboard Settings route, but checking for updates doesn't show v.22.214.171.124 and just says I have the latest version (126.96.36.199).
So then I put v.188.8.131.52 into the 'updates' directory per concrete5 instructions (both unzipped and zipped).
Dashboard still doesn't see it.
I then changed the config file to point to 184.108.40.206 which breaks the site.
