I had the same problem to show the tags on blog post.
My Settings: Article Document -> Enable Comments:No
i solved the problem in the article.class.php
search for line: 46
if ($this->xpdo->getOption('commentsEnabled',$settings,true)) {
the else statement is empty
} else {
$this->xpdo->setPlaceholder('comments_enabled',0);
}
i paste the following lines in the else part from if statement
$this->getTagsCall($settings);
$this->xpdo->setPlaceholder('comments_enabled',0);
/** @var ArticlesContainer $container */
$container = $this->getOne('Container');
if ($container) {
$container->getArchivistCall();
$container->getLatestPostsCall();
$container->getTagListerCall();
}
This show tags and latest post in default sample.ArticleTemplate.
Hope this helps.
