WP Super Cache breaks Leaflet Maps Marker plugin

Hi,

I am the developer of the mapping plugin “Leaflet Maps Marker plugin” (mapsmarker.com) and users have reported an incompatibility with your plugin.

Here is the issue: when WP Super Cache is not configured properly, the following message is output in the console:

se1.php in wp-content/advanced-cache.php must be fixed! –>)

Additionally, the following text is added to the end of each file:
<!– WP Super Cache is installed but broken. The path to wp-cache-phase1.php in wp-content/advanced-cache.php must be fixed! –>

This is a problem for me, as my layer maps produce a jsonp-output and your comments is breaking its validity (and my layer maps as a consequence). Here is an example output:

jsonp({“type”:”FeatureCollection”, “features”:[ ]});<!– WP Super Cache is installed but broken. The path to wp-cache-phase1.php in wp-content/advanced-cache.php must be fixed! –>

Can this comment only be added if the plugin is active? I would suggest changing \advanced-cache.php from

function wpcache_broken_message() {
    if ( false == strpos( $_SERVER[ 'REQUEST_URI' ], 'wp-admin' ) )
        echo "<!-- WP Super Cache is installed but broken. The constant WPCACHEHOME must be set in the file wp-config.php and point at the WP Super Cache plugin directory. -->";
}

to

function wpcache_broken_message() {
    include_once( ABSPATH . 'wp-admin' . DIRECTORY_SEPARATOR . 'includes' . DIRECTORY_SEPARATOR . 'plugin.php' );
    if (is_plugin_active('wp-super-cache/wp-cache.php') ) {
         if ( false == strpos( $_SERVER[ 'REQUEST_URI' ], 'wp-admin' ) ) {
             echo "<!-- WP Super Cache is installed but broken. The constant WPCACHEHOME must be set in the file wp-config.php and point at the WP Super Cache plugin directory. -->";
         }
    }
}

It would really be great if you could help me on this!
best & thx,

Robert
