Count() no longer returns null.
Incompatible with PHP > 7.2

<core>/wp-admin/user-edit.php on line 285:

<?php
if ( count( $_wp_admin_css_colors ) > 1 && has_action( 'admin_color_scheme_picker' ) ) :

<?php
if ( is_array( $_wp_admin_css_colors ) && count( $_wp_admin_css_colors ) > 1 && has_action( 'admin_color_scheme_picker' ) ) :

Fixed count(): Parameter must be an array

Can you provide steps to reproduce this? Using a stock install of WordPress, I'm unable to replicate it. It would appear as though a piece of custom code is overriding the global variable $_wp_admin_css_colors and that is causing the notice for you.

You're right. It's a plugin error while overwriting the $ _wp_admin_css_colors global variable.

Thank you @jorbin
