In my case the problem seems to be WooCommerce.
When I create a new Page with a Textblock the resulting code looks like this:
<div class=”container”>
<div class=”container_inner default_template_holder clearfix page_container_inner”>
<p>Test</p>
</div>
</div>
When I set the page as my default shop page in WooCommerce, the code of this block changes to
<div class=”container”>
<div class=”container_inner default_template_holder clearfix”>
<div class=”page-description”>
<p><!– wp:paragraph –></p>
<p>Test</p>
<p><!– /wp:paragraph –></p>
</div>
…Additional WooCommerce-Stuff…
I have the newest WooCommerce-Version installed.
As WooCommerce is not a small and special plugin, please check this, thanks.
I also noticed that many shortcodes which work fine without Gutenberg lead to an error when storing the page now. Is there already a post or bug-report for this or should I open one?
Thanks
