Installed fresh Elgg 1.8.16, Plugins all think I'm running 1.8.15

I have a fresh install of Elgg 1.8.16.  I am trying to install a new plugin that requires 1.8.16. When I go to the plugins, every plugin reports me as being on Elgg 1.8.15, so I can't install this plugin.  

In version.php, it says I'm on 1.8.16 and has version date 2013051700.  In the database, in elgg_datalists version says 2013030600.  When I run upgrade.php, it shows the spinning loading symbol and then loads the activity page and nothing changes in the database.

What can I do to make Elgg recognize I'm running 1.8.16?
