Call to undefined function get_blog_details()

I’m sorry.
In a single-site, you get such an error.
I can not currently update. I can be updated after 8 hours.
If you are in a hurry, Please correct as follows function siteurl from the 648 line of the inc/MediaFromFtp.php

function siteurl(){
	if ( is_multisite() ) {
		global $blog_id;
		$siteurl =　trailingslashit(get_blog_details($blog_id)->siteurl);
	} else {
		$siteurl = site_url('/');
	}
	return $siteurl;
}

Excellent as it worked with the lines you added.

Thank you

Ed.
