For the time being, I would ask the host, what he would say, how to solve the problem. I think, things would be easier, if gzip compression would be disabled. So I would disable gzip compression in LocalSettings.php for the time being.

There are also some guys from Wikimedia Foundation, who come around here sometimes; maybe they know more...
