Comecei a fazer este curso há alguns meses e interrompi após travar em uma parte que já nem mais me lembro. Ao retornar, decidi começar do zero: deletei a pasta anterior e criei novo WP, inclusive na versão indicada. No entanto, ao tentar ativar o tema, apareceu este "pequeno" erro:
Fatal error: Uncaught ArgumentCountError: array_merge() does not accept unknown named parameters in C:\xampp\htdocs\alura-intercambios\wp-includes\widgets.php:1261 Stack trace: #0 C:\xampp\htdocs\alura-intercambios\wp-includes\widgets.php(1261): array_merge(wp_inactive_widgets: Array) #1 C:\xampp\htdocs\alura-intercambios\wp-includes\widgets.php(1216): retrieve_widgets(true) #2 C:\xampp\htdocs\alura-intercambios\wp-includes\class-wp-hook.php(289): wpsidebars_changed('Twenty Twenty') #3 C:\xampp\htdocs\alura-intercambios\wp-includes\class-wp-hook.php(311): WP_Hook->apply_filters(NULL, Array) #4 C:\xampp\htdocs\alura-intercambios\wp-includes\plugin.php(478): WP_Hook->do_action(Array) #5 C:\xampp\htdocs\alura-intercambios\wp-includes\theme.php(2974): do_action('after_switch_th...', 'Twenty Twenty', Object(WP_Theme)) #6 C:\xampp\htdocs\alura-intercambios\wp-includes\class-wp-hook.php(287): check_theme_switched('') #7 C:\xampp\htdocs\alura-intercambios\wp-includes\class-wp-hook.php(311): WP_Hook->apply_filters(NULL, Array) #8 C:\xampp\htdocs\alura-intercambios\wp-includes\plugin.php(478): WP_Hook->do_action(Array) #9 C:\xampp\htdocs\alura-intercambios\wp-settings.php(540): do_action('init') #10 C:\xampp\htdocs\alura-intercambios\wp-config.php(95): require_once('C:\xampp\htdocs...') #11 C:\xampp\htdocs\alura-intercambios\wp-load.php(37): require_once('C:\xampp\htdocs...') #12 C:\xampp\htdocs\alura-intercambios\wp-admin\admin.php(34): require_once('C:\xampp\htdocs...') #13 C:\xampp\htdocs\alura-intercambios\wp-admin\themes.php(10): require_once('C:\xampp\htdocs...') #14 {main} thrown in C:\xampp\htdocs\alura-intercambios\wp-includes\widgets.php on line 1261
