I was editing my profile and when I tryed to edit my website I got an error saying that http://www.lti.usp.br/~flaviotruzzi is not an valid url…
I’m guessing Liferay tries to contact that page to see if it exists but the page doesn’t actually exist or work (atleast from over here). The domain can’t be found on the few nameservers i’ve tried quickly. www.usp.br can be found but not lti.usp.br or www.lti.usp.br.
Is it the correct address?
my BIG apologize 
it changed to lti.pcs.usp.br
