After a little delay, I finally decided to do the 2.3.2 upgrade. I've upgraded many times before. No big deal.
I upgraded, copying the files, ran the update script, all the usual.
Went to the admin pages... 'you're running 2.3.1.. please update'
Cleared browser cache. Restarted browser for good measure... navigated to an admin page I haven't looked at in a while... all show 2.3.1
Reinstalled a few times. No joy.
Looked at version.php in wp-includes. It claims it's 2.3.2
Something screwy is happening....
