I have indeed RTFM'd, but am willing to accept a link if not a direct answer to how I make an error (that started turning up just before I inherited this project) go away:

Notice: Undefined index: [line #] in civicrm_handler_field_state->render() ...

I see it on other people's sites so I know there must be a few people who would love to know how to fix this.

Thanks!

This is a generic PHP message saying that the code is trying to access a variable that doesn't exist. They are usually harmless, sometimes not.
To get rid of it you need to try to understand what the code is attempting to do. Often the fix looks like this:
Replace something like

Code: [Select]

if ($foo['bar'])with

Code: [Select]

if (!empty($foo['bar']))

Awesome, thanks.

I was hoping that it was something obvious to do with the ongoing battle between CiviCRM and OG rather than requiring that I go in and modify the code, but c'est la vie.
