WP/Visual Editor Breaking (gzip thing)

Hey, gents.

I’ve been running my blog for about a month now and very abruptly the tiny_mce editor stopped working. I temporarily fixed this by setting $supportsGzip = FALSE;

I own the server and manage it on my own. The problem mentioned that the server was sending compressed content all the time. I’ve never enabled this capability, either through PHP or apache. Yet there I am, look at gzipped headers coming from apache.

What am I missing? (This server runs the PLESK CP w/ a customer PHP5.2.5 install)
