After installing Latest News Enhanced on my J4 development website I was unable to save any parameters. The LNE developer Olivier Buisard has tracked down the problem to an Atum override added by Fabrik:
administrator/templates/atum/html/layouts/joomla/edit/params.php
He says that with the override enabled each tab has double the parameters and therefore won't save and that the override is also interfering with some of the Joomla core functionality.
