Control Panel Title Displays "javax.portlet.title.160"
As part of our community verifier program, I am taking a look at this issue. Can you provide screen shot of a page where instead of Portlet Title you saw this language key or part of source code where you saw this key being used?
Liferay 6.1 GA1 by default has new Control Panel theme. As I see your screnshot is from old theme. Can you describe me how did you managed to turn it on in LR6.2?
It's seen on liferay.com. If liferay.com not running 6.1GA1, then this issue could be closed.
Liferay.com is not on LR6.1 (yet ) so this ticket can be closed.
