Upgrading to concrete220.127.116.11
First, I tried the Dashboard Settings route, but checking for updates doesn't show v.18.104.22.168 and just says I have the latest version (22.214.171.124).
So then I put v.126.96.36.199 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 188.8.131.52 which breaks the site.
