Jetpack

Quick summary

I just noticed that on the Modules page (/admin.php?page=jetpack_modules) and the Debug page (/admin.php?page=jetpack-debugger) I'm seeing a PHP deprecation notice:

Deprecated: strip_tags(): Passing null to parameter #1 ($string) of type string is deprecated in …/wp-admin/admin-header.php on line 41

This is the error location in admin-header.php:

get_admin_page_title();
$title = strip_tags( $title );

Apparently Jetpack isn't defining any $title global variable for these custom admin pages, and get_admin_page_title() isn't able to generate one because the Debug and Modules admin screens are not registered in the admin menu.

The TITLE tag for these admin screens shows as:

<title> &lsaquo; My Site &#8212; WordPress</title>

Note there is no page title included here.

Steps to reproduce

1. Enable PHP 8.2 (at least).
2. Activate Jetpack
3. Enable SCRIPT_DEBUG
4. Go to the the Blocks or Debug admin pages for Jetpack.
5. See notice.
