This is normal content in a page that includes a Voice module (Posts, default settings).
This page template is set to “Template standard” and the module does not appear.
If the page template is set to “Modules” this content disappears, and the module appears only as an empty box. SEE HERE
Disabling all plugins does not change that.
Another thing is that in the editing page the Modules block does not appear automatically even if they exist and the visualization is activated in the page view options. This did not happen until recently.
