Someone elsewhere posted a simple css fix so the wordpress core update message won’t display (the chief concern I have for my customers).
Edit the wp-admin.css (under the wp-admin directory) and add “display: none;” to #update-nag section. (it’s near the very bottom)
Worked like a champ and was very easy.
The plug-in (http://wordpress.org/extend/plugins/disable-wordpress-plugin-updates/) oddly enough caused severe performance issues on my blogs causing page timeouts and extremely slow page loads. Deactivate the plugin, all is good, Activate it, performance issues abound. It would happen 1 out of every 4-6 page loads. Strange.
Side note – I use A LOT of plugins, so this could be a result of a combination of plugins, not that this one is the sole cause. But wanted to provide a heads up if anyone else experienced the same thing.
