nordicjoomla I got your point but others would like to have a heading on top of page in H1 so we temporarily put the H2 for the article title there.
You can easily override it by copying 3 files in this path:
/templates/ja_purity_iv/html/com_content/article/
paste into:
/templates/ja_purity_iv/local/html/com_content/article/
(create this path folder if it doesn't exist now)
Then edit each file to replace the H2 by H1 tag.
For example, with default layout, you will edit file: ``/templates/ja_purity_iv/local/html/com_content/article/default.php`
change:
<h2 itemprop="headline">
<?php echo $this->escape($this->item->title); ?>
</h2>
to:
<h1 itemprop="headline">
<?php echo $this->escape($this->item->title); ?>
</h1>
The same with other 2 files.
