You can thank me with a 5 star rating. 😉

There is nothing destroyed because the saved relationships are still there. You can just wait some hours and the next fix will be online.

I think I don’t have to comment the rest.

There are at least two options because the code is outdated:

1. You could use the addon MslsMenu -> https://ww.wp.xz.cn/plugins/mslsmenu/
2. or rewrite the code a bit:

add_filter( 'wp_nav_menu_items', 'zw3_lang_switcher_menu_item', 10, 2 );
function zw3_lang_switcher_menu_item( $items, $args ) {
	if ( class_exists( lloc\Msls\MslsOutput::class ) && 'Primary' == $args->menu->name ) {
		$obj = lloc\Msls\MslsOutput::init();
		$arr = $obj->get( 1 );
		if ( ! empty( $arr ) ) {
			$items .= '<li class="menu-item lang-switcher menu-item-type-custom menu-item-object-custom">' . implode( '</li><li class="menu-item menu-item-type-custom menu-item-object-custom">', $arr ) . '</li>';
		}
	}
	return $items;
}

Just to be sure: This a multisite (configured with subdirectories) with two sites – one English and one German – and not to single sites, right?

Das ist sozusagen der erste Schritt. Danach muss man im WordPress Admin unter Werkzeuge -> Netzwerk-Einstellungen den nächsten Schritt machen und sich den Rest der Konfiguration ausgeben lassen.

Ich hab nur eine englischsprachige Anleitung hier: https://codex.ww.wp.xz.cn/Create_A_Network

This is kind of strange but let me understand what’s going on:

– Is that in every site the case? Like A does not see B and B does not see A?
– Do you use custom code for filters or action provided by MSLS?
– Does return back to 1.0.8 (the latest stable here) or 1.2 (at Github https://github.com/lloc/Multisite-Language-Switcher/releases) resolve that problem?

You have probably MslsMenu installed. The problem was how the addon called the options page. I could correct this in MSLS directly.

You can set the user language for every user (that’s why I removed it from the plugin). There is just one cave-eat: You should not go to the permalinks-section to not to refresh them with the language of the user.

OK, try the new release! 😉
