 * After the latest update I started getting a string of both errors and error messages.
 * I have debugging turned off – set to false.
 * But I keep getting Undefined index or undefined variable and it seems to happen
   almost randomly. If I disable one plugin, then another error pops up for a different
   plugin. Disabling and then re-enabling does not help. I don’t understand how 
   this happened or what it means. I’m about to just kill the entire install – which
   will hurt, but I’m sick of the errors.

 * Turn off the PHP display_errors setting. You should not have a live site setup
   to display errors in the first place. That is a debug setting, useful for development,
   but useless on real production sites.
 * Notices are ignorable errors that normally don’t display at all.

 * Hey, do you know if hostgator turns this on by default? I’ve not turned it on
   or enabled it.

 * It probably is on by default. You may need to ask your host how to turn it off.
