**Describe the issue / Steps to reproduce:**  
I upgraded from Bluespice free 3.5 to 4.5.4 (installation of webserver from scratch on a new machine) and managed to transfer the mariaDB.  
Main page and all pages in namespace (Seiten) are present, all users are present. But somehow I lost my other namespaces and their pages.  
When I try to add a namespace I get a warning “internal server error”.  
Also, all the attached files are missing. Do I have to copy them separately?

**Expected behavior:**  
After migration of mariaDB I expect to find all pages of my existing wiki including other namespaces than (Seiten).  
I expected the attached files to be part of the database.

**What was the error message/error log?**  
“internal server error” when trying to create a namespace

**System info:**

- OS: Linux mint 22 Cinnamon
- Server: Apache2
- PHP: 8.1
- Database: mariaDB 10.11.8
- BlueSpice version: BlueSpice free 4.5.4
- Browser version: Mozilla Firefox 135.0

I have to add that this problem persists after starting a new installation of BlueSpice Free 4.5.4 on a clear database. Have started a different thread as the headline would be misleading otherwise.

After running update.php _again_ the create-namespace-topic seems to be fixed.
