Hmm, it seems like the connection between blog 1 and blog 2 had disappeared, although blog 3 still linked to both other blogs just fine.

Reconnecting helped – I guess I’ll just have to connect all posts and pages manually now.

Problem solved – thanks a LOT for your help and patience.

Yes, that is correct.

Just tried that – I don’t see any changes or consequences.

I cannot help if I don’t get answers 😉

I thought I did that with “That is correct.” 🙂

Commenting out that line got rid of the error popping up when trying to edit/ save a post. It also returned the hreflang-tag on the home page of the default blog. The home pages of blog id 2 and 3 now have a double hreflang reference – both to the domain itself.

Cross post references (both links and hreflang connections, between interlinked posts and pages) still aren’t present.

There’s this:

}
function my_msls_blog_collection_get( $arr ) {
    $arr = array();
    foreach ( array( 1, 2, 3, ) as $id ) {
        $arr[$id] = get_blog_details( $id );
    }
    return $arr;
}
add_filter( 'msls_blog_collection_construct', 'my_msls_blog_collection_get' );
function my_print_something() {
    $blogs  = MslsBlogCollection::instance();
    $mydata = MslsOptions::create();
    foreach ( $blogs->get_objects() as $blog ) {
        $language = $blog->get_language();
        if ( $blog->userblog_id == $blogs->get_current_blog_id() ) {
            $url = $mydata->get_current_link();
        }
        else {
            switch_to_blog( $blog->userblog_id );
            if ( 'MslsOptions' != get_class( $mydata ) && !$mydata->has_value( $language ) ) {
                restore_current_blog();
                continue;
            }
            $url = $mydata->get_permalink( $language );
            restore_current_blog();
        }
        $language = substr( $language, 0, 2 );
        printf(
            '<link rel="alternate" hreflang="%s" href="%s" />',
            ( 'us' == $language ? 'en' : $language ),
            $url
        );
    }
}

Neither this code nor the language settings had changed around the time that the errors occured for the first time, though.

The plugin is network-active and I didn’t add any new sites.

My bad, it was a wrong setting indeed.

It worked like a charm, thanks for your help!
