Hi Aray

Have you any menu items that link to the posts in the older environment? Is it only with a menu item that modules can be assigned/unassigned without a module manager extension.

Hello Ciaran,

thank you for your reply.

But I don't understand why the error occurred when starting dravecore.de online and beyond, and why I suddenly need a module manager to fix it?

Please take a look at the subdomain page I created, on which I played the backup of May 2023, where you can easily access the posts in the news module "Spectrum" as a post!? https://backup.dravecore.de

Hello

Assuming I understand you correctly, this is how Joomla handles module assignments. For Joomla to be able to assign/unassign a module on any particular page it requires that the page have a menu item related to it. If no menu item exists the module assignment of the parent page is used. As I see it your solution would be one of the following..

1. Create a hidden menu. A quick Google search should give you plenty of information on this.
2. Use an extension that gives more elaborate module assignment possibilities. By far the most popular is... https://extensions.joomla.org/extension/advanced-module-manager/
