safari can't open the page because the server unexpectedly dropped the connection
This has started happening for most wordpress.com blogs I try to view. They load fine in Firefox and Chrome but in Safari I get 'safari can't open the page because the server unexpectedly dropped the connection'. I have Safari 6.1.2. I've tried deleting cookies.plist from my Library, emptying the cache and restarting; no joy. Any suggestions please?
