Thanks! I did have that set in LocalSettings.php and stared right past it. But before I read this response I did change automatic REMOTE USER to eliminate the error.

You might have error reporting enabled in LocalSettings.php (it's a common recommendation for debugging). Something like error_reporting( -1 ); ini_set( 'display_errors', 1 );

Anyway, it's better to fix the underlying issue when possible. What version of automaticREMOTE_USER are you using? It looks like there was a fix for some strict standards errors about a year ago: https://bugzilla.wikimedia.org/show_bug.cgi?id=38369
