 Hi! I was updating an automation script and, while debugging, I noticed
 that the line **1075** of the file ''\wp-includes\l10n.php'' performs a
 comparison operation between two array elements before verifying the
 existence of both (i.e. one is verified, the other isn't and this one
 throws an error):

 Current line 1075:
 } elseif ( ! isset( $src_url['host'] ) || $src_url['host'] ===
 **$site_url['host']** ) {

 **Proposed change:**
 } elseif ( ! isset( $src_url['host'] ) **|| ! isset( $site_url['host'] )**
 || $src_url['host'] === $site_url['host'] ) {

 I hope this helps.

 Best regards,

 Vick
