I think I have found out the issue.
A third party plugin caused the issue.

I had a plugin activated for custom 404 pages.
I have deactivated it now. Seems to work fine now.

Thanks for your help & and I´m sorry for the circumstances.

Regards,
Alex

Hello Robin,

thanks for your reply!

I have done following:
dashboard > settings > permalinks > just hit save (without selecting anything new)

I have /postnames selected.
