I just wanted to report that I stumbled on the error message in the subject browsing through the Error Log. I'm currently using 2.0.11 and there were hundreds of entries of this particular error.
Digging in the forum I found a thread from 2011 (https://www.simplemachines.org/community/index.php?topic=427245.0) that suggests to comment out a line in Source/Load.php as show here:
// Default language directories to try.
$language_directories = array(
$settings['default_theme_dir'] . '/languages',
// $settings['actual_theme_dir'] . '/languages',
);
Seems to work without consequences, but we have to be vigiliant as it doesn't look like the actual cause and the proper solution to the problem were ever found.
I hope this post helps other people who stumble on this issue.

You should be on 2.0.15, I would update right away.
Do you mean that 2.0.15 explicitly solved the problem?
No, and I'm actually unsure what the actual cause of the problem is - it's not that code, even if it could use an if statement to check that it's not empty, IMO it should never really be empty.
What theme are you using?

You probably better ask for support over SMFPacks since you're paying for the theme
Some themes use functionality around inheriting from other themes. I doubt that this one does because I don't recall Nibogo ever using it (far as I remember only Bloc ever did), so in the interim just commenting out the line you have is fine.
Understood Arantor. Thank you.
