Hi,
we had migrated our website from the previous Joomla to the present Joomla 4. Most articles have the "read more" link that leads to the full article.
When you click on the "Read more" button the full article does not show but an empty page with a black bar across it.
See the link in the URL provided, you can test on the first page already.
The same symptom is when linking to a new page within an article.
Thanks for any help...
