Thank you for your help!
Now the MMM-ip works!

But I have another question:
Have it to consider something at the wuforecast module?
I set it up and now it shows only that it lades, but nothing changes :(

I wanted to install some modules.
I’m always on the instructions of the modules on Github.
After the “installing” the mirror has a problem, displays is/shows only a black screen.

What could that be?
Can someone help me?
Would be best in German :)
