Duplicate ID defined in some instances

[trepmal]

This ID:

nginx-http-concat/cssconcat.php

Line 136 in cda3f4c

echo apply_filters( 'ngx_http_concat_style_loader_tag', "<link rel='stylesheet' id='$media-css-$idx' href='$href' type='text/css' media='$media' />\n", $handles, $href, $media );

the do_items() function is called twice, once for the head, once for the footer. This means the loop that sets the number in the ID is run twice, resetting on the second instance, resulting in the doubled ID.

Simplest fix might be to increment the number sufficiently on one of the loops. e.g. adding between these lines

nginx-http-concat/cssconcat.php

Lines 110 to 111 in cda3f4c

	foreach( $stylesheets as $idx => $stylesheets_group ) {
	foreach( $stylesheets_group as $media => $css ) {

 if ( $group ) { $idx += 1000; }
