shutdown function flush output buffer

Hi, I’ve been building a wordpress site with this plugin and it has been difficult to develop with because the exception thrown on line 191 of mgcl_core.php when the output buffer is flushed slows my php debugger. I suggest changing this code to

while (ob_get_level() > 0) {
    ob_end_flush();
}

To avoid the exception and avoid using the ‘@’ operator.
