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/

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

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.

Ciaran

Hi Cirara,

No! As you can see with backup.dravecore.de, I used the one-page menu. It was easily possible to access the three posts from the news module on the home page!
Unfortunately, my provider can only provide me with PHP version 8.1 at the end of February, so I could not use the menu manager at the moment. Which is very annoying!

Hello

May I suggest sending temporary administration access to your Joomla installation to info@joomla51.com and I will create the hidden menu item for you.. For our reference please paste a link to this post in your email.

I sent you a login. Please use for the upstream login:

Hello

The above details appear to be only for your htaccess on your Joomla administrator folder. When we try to access your Joomla administration with the same details we get the following notice (we do not appear to have received any details via email).

Username and password do not match or you do not have an account yet.

Ciaran

Hello Ciaran,

as you can see in the screenshot, I had created an administrator access for you. I have now sent you a new login. Note the first login with:
user: admin
Password: joomla100!

Hi Ciaran,

haven't you read my chat message yet?

Thank you Aray

Could I ask you to allow us access to your extensions manager. There appears to be an issue with your SEF URLs causing menu items to give a 404 error.

Ciaran

Is the status "Manager" now enough for you or do you even need the "Super User"?

Aray

Hi Aray

As long as we have access to your extension manager in case we need to update anything and your global configuration so we can access your SEF URL settings.

Ciaran

Hi Ciaran

do I understand correctly that you can fix the problem now?
Also that with the delayed slider show?

Aray

Hi Ciaran

and please tell me why this problem arose.

Aray

Hi Aray

We are still unable to access your global configuration or extensions manager.

Ciaran

What else do you need? The "SuperUser Status"? Or what?

I just granted it to you!

just

Thank you

This issue should be now resolved. We have created a hidden menu item for your blog pages and disabled 'Use URL Rewriting' in your global configuration.

Ciaran
