While the flu kept me in my bed, it seems something else also affected the webserver of the FSDeveloper website. I just noticed it today when I sat behind my computer again and I have informed support about it. So hopefully the site will be running soon again. As this kind of problems seem to happen semi-regular we will already try to investigate the sources of it.
But if you excuse me now, I will retreat from the PC back into the bed, as I am not fully recovered yet.
EDIT: By now the site is up and running again.
