futtta on "[Plugin: Autoptimize] Confict with Dynamic To Top"

If you can open up wp-content/plugins/autoptimize/classes/autoptimizeStyles.php and on line 271 replace

//Minify
if (class_exists('Minify_CSS_Compressor')) {
	// legacy
	$tmp_code = trim(Minify_CSS_Compressor::process($code));
} else if(class_exists('CSSmin')) {
	$cssmin = new CSSmin();
	$tmp_code = trim($cssmin->run($code));
}

with:

//Minify
if (class_exists('Minify_CSS_Compressor')) {
	// legacy
	$tmp_code = trim(Minify_CSS_Compressor::process($code));
} else if(class_exists('CSSmin')) {
	$cssmin = new CSSmin();
	if (method_exists($cssmin->run)) {
		$tmp_code = trim($cssmin->run($code));
	}
}

This should fix the "white page of death issue" that was due to a CSS minifier conflict.

If this is confirmed to be working, I'll add it to 1.8.2 which should be out later this month.
