404 and content.

https://aws.lohray.com/wptr/wp-content/plugins/pretty-simple-progress-meter/css/psp_styles.php is a php script that generates some css. The plugin does not work as the php returns a 404 header.

However, it also returns the content. I have been checking it using firebug.

Any ideas on how to resolve this?

Thank you ??

 	$heightOption = get_option('height_option');
 	$heightOption = ($heightOption == "") ? '30' : $heightOption;
 	$widthOption = get_option('width_option');
 	$widthOption = ($widthOption == "") ? '30' : $widthOption;
 ?>
div.prettysimpleprogresswidget {
	padding:0;
	margin:10px 0 0 0;
	}

div.prettysimpleprogresswidget div.show {
	height:<?php echo $heightOption; ?>px;
	width:<?php echo $widthOption; ?>px;
	padding:0;
	margin:2px 6px 0 0;
	float:left;
	background-color:#<?php echo $meterOption; ?>;
	background-position:center;
	background-repeat:no-repeat;
	}

is a part of the php that is generating it.
