How to display module on all pages
In order for the module to be displayed on all pages, not only on the page where it was initially added, it is necessary to enable displaying on all pages.
Switch DNN to the Edit mode. Find the module on the page and select DNN module settings > Advanced settings > Display Module on All Pages. Enabling this setting will add a module to all pages.
Notes:
It is recommended in DNN module settings to disable displaying of the module container in Page settings> Display container.
Set the module permissions to page default so the module is visible to all users.
