No content in backend

[olih]

Hello,

l have an installation with 2.3.1.8.

A few days ago I wanted to make some text changes. After logging in I realized that all fields on the page are empty. There is no content to change in the backend. In the frontend the content is still shown.

Does anyone have an idea how this could happen?

Does nobody have an idea?

It seems that backend and frontend are not connected anymore.

Even if I enter some Content in a filed it is not shown in frontend.

Ok, I found the problem. My customer moved sites and changed templates.
