Line 389-390:

What is the typo?

I believe he is suggesting the Subsubtitle is spelt incorrectly when in fact it is not or at the very least be spelt Sub-subtitle though I do not see it being a problem..

Unless there is something else that i cannot see

   

Could be that the L_ would make the template lang var {L_L_WHATEVER?}

Edit:

After looking at the .php files - It's not that either.

So whatever he / she is on about - who knows?
