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

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 :-)
