ob_end_flush error

Hi,

I get the following notice showing up in the bottom of the page in the WordPress dashboard when debugging is turned on. Not a major issue, but slightly annoying!

Notice: ob_end_flush(): failed to delete and flush buffer. No buffer to delete or flush in [PATH]/wp-content/plugins/vcaching/vcaching.php on line 168

I’ve temporarily fixed it by tweaking the code on this line to:

if (ob_get_contents()) ob_end_flush();

Would be great if you can add to a future release.

PS – Great plugin, thanks!
