Hello support_staff and good morning ...
... thank you for your offer and help - I´m new in building sites on wordpress - is it possible for me to solve the problem by my own with your support ?!?
If it´s easier and necessary to give you a temp access - I will do this, but HOW can I share this
Thank you again for your help ... Stefan

Hello fotografie,
sorry but some changes needs to be made at the backend-code. Sharing the temp access will make it easier.
For sharing the temp access-
1) Go to users option in your wordpress dashboard.
2) Add a user with a user-role "admin"
3) create a password.
4) save.
For reference you can see here- https://postimg.org/image/91ag7r7i1/
Now you can mail this newly created username and password to lizarweb[at]gmail[dot]com
Thanks.
