Data not updating in Single section editors

Hi. I have an issue with single section editors in a new installation of CMSB.  I've never had this issue before, so it's confusing.

When I enter data and click save, the data definitely saves the first time (I get the 'record saved' dialog) but all the fields in the editor show as blank.  

Also, only the first set of data saved shows up - if I change the data in the fields, the MySQL Table count goes up by one increment, but the live content doesn't change.

Any idea what's going on? It's an identical install to what I've used before.

The dump from the Server info section is below, and I'm using Chrome v.47 (though it does the same in Firefox and in Safari)
