It looks like the forum is working again!!!
Finally, after much sweating and frustration.
I'll later tell teh whole story, but for now I'll kepp it with this:
The hosting company owners did have a dispute, one left and took with him some servers and the administration and pulled out the plugs.
So all sites went dark. And after much telephone calls etc. I manages at least to get the data back.
Then I needd a new server, the domain name needed to be transferred. Server setup, database reload etc etc.
I do hope that all works now!
