It happened this way.
This server is located in Denmark.
Unfortunately, it is this area that have been hardest hit by the huge masses of water. So host company moved it to another location.
It went pretty fast, you could say.
The server should have PHP5 installed, but it was not, and I didn’t know about it and updated WordPress to the latest version. Then stopped working anything. So I had to delete files and install back to the older version.
Now my site has returned. But you still cannot download files from this server yet.
