The CMS Questions
20

Ok so now its the future and the Meta Tags Plugin has been updated for Kirby 2.5.7 which has meant some slight changes to the syntax it uses because I found an issue.

Heres the updated version of the fallback above, using the new syntax, in case its useful to somebody.

// SEO Settings
// Global
c::set('meta-tags.default', function(Page $page, Site $site) {
    return [
        'title' => $page->isHomePage()
          ? $site->seotitle()
          : $page->seotitle().' | '.$site->seotitle(),
          'meta' => [
              'robots' => 'index,follow,noodp',
              'description' => $page->isHomePage()
                ? $site->seometa()
                : $page->seometa(),
              'keywords' => $page->isHomePage()
                ? $site->seokeywords()
                : $page->seokeywords(),
              'robots' => 'index,follow,noodp',
          ],

               if($image) {
                 return $image->focusCrop(1200, 630)->url();
               } else {
