Warning: filemtime(): stat failed for

Hi,

My homepage and all pages on the https domain (http does not) are generating the following error:

Warning: filemtime(): stat failed for https://site/wp-content/themes/report/css/main.scss.php in /home/name/public_html/wp-content/themes/report/functions/wp-sass/wp-sass.php on line 127

Line 27 in said file is:
$full_cache[ ‘updated’ ] = filemtime( $sass_path );

Expanded:

// update cache creation time
$full_cache[ ‘updated’ ] = filemtime( $sass_path );
file_put_contents( $cache_path, serialize( $full_cache ) );
file_put_contents( $css_path, $full_cache[ ‘css’ ] );

Any ideas?

Thanks,
Josh
