joomla 2.5 tp=1 shows "object arguments" instead of real position names

Question

I have seen different templates that doesn't let us see their position names. When I add ?tp=1 to website link, they show [object arguments] instead.

I think these frameworks use T3 template engine (?). [what ever T3 is, it doesn't matter for me]

I'm not looking for these answers:

• Please tell me what the template name is? Visit its official demo url (for example http://joomla17-templates.joomlart.com/ja_elastica/?tp=1 or another demo) This is not a real answer!
• Update your template! This is not also a working answer. It doesn't matter to template updgrades. Because I can see somebody in the link that has updated his template, but that hasn't worked.

UPDATE

Unfortunately also the official demo of the template has the problem: http://demo.bowthemes.com/bt-arise/?tp=1

Answer 1

Your second link had the answer -

I enabled that plugin, 'System - Language Code' and lo and behold, the template module positions were back.

I'd start with that because the T3 framework definitely displays module positions.
