Paolo, yes, Core is 1.5.8 and all other add-ins updated to very latest as of yesterday.
Guust, no, for the truncated domain problem, if you click on the link you get whatever is shown in the status bar – half the domain – so you’d end up at an invalid domain. The truncated domain name never becomes the full domain name, no matter how long you wait/hover.
This happens in Chrome and IE and Firefox.
For the missing www, I’ve just seen that in Chrome, if you hover and wait long enough it becomes www in the status bar. At the moment is seems to work OK in IE and Firefox – www always shown.
But I cannot tell if clicking before the www appears takes you to the www domain or to the non-www though – the hosting is set to change domain.tld to http://www.domain.tld.
The www/no www is not a huge problem. Since it only appears to affect Chrome I’m not really bothered. But the truncated domain is a big problem though!
