There is undefined index in strip_fragment_from_url function for

 $parsed_url['path']

path should be checked to be available. Simple check needed:

if ( ! empty( $parsed_url['path'] ) )

file: wp-includes/canonical.php line 570

Hello @betterstudio, welcome to WordPress Trac!

So far strip_fragment_from_url() is only used in redirect_canonical(). What URL are you trying to access to get this warning?

Hi @ocean90
I can't remember it now because i saw it 6 week ago in one of our customers site!

It does not matter! You can check this code: {{{#!php
<?php

strip_fragment_from_url( '​http://betterstudio.com' );

}}}

That function will make a warning!

Notice: Undefined index: path in .../wp.dev/wp-includes/canonical.php on line 570

In the function the other array index are checked except this one so as suggested on the ticket this will avoid problems :-)

In 41257:

Canonical: Check first before attempting to include a 'path' value in the URL in strip_fragment_from_url().

Props Mte90.
Fixes #40542.
