My site looks fine on my machine and at least another one using my connection, but won't show anything than a blank page from anywhere else. After displaying fine for some time through various themes, this has started after extra-careful K2 theme customization (I'm a total newbie), but is affecting now any active theme including the default. I've tried deactivating all plugins but no way.
Update - this has been driving me nuts till 5 minutes ago, when someone happened being able to see it. Can more people confirm my site shows up? Btw, how shouldn't I now fear upgrading from 2.0.2 to 2.0.3 version? Many thanks.
