Hello
Sitemap of "Yoast / wpSEO" gets broken with msg:
This page contains the following errors:
error on line 1 at column 7: XML declaration allowed only at the start of the document
Below is a rendering of the page up to the first error.Deactivate the advanced access manager Plugin fix this.
My temporary solution for this:
aam.php on line 120:

self::$_instance = new self;
