WP-Config – define(‘WP_DEBUG’, false); it had been ‘true’ . This removed the notice from back-end and front-end of site.
[10-Jun-2014 16:31:24 UTC] PHP Notice: register_uninstall_hook was called incorrectly. Only a static class method or function can be used in an uninstall hook. Please see Debugging in WordPress for more information. (This message was added in version 3.1.) in wp-includes/functions.php on line 3245
I have checked the functions.php and no longer see this on line 3245.
I am going to try again to update to 3.2 today. I ran out of time last night to change all the site settings from 3.1 to 3.2.
Is there an easier way to upgrade without having to re-set each setting?
