Which line ?

Hello there!
First of all, very useful and easy to use plugin!
I have a question though:
I have this message :

Warning: More than one text-domain is being used in this theme. This means the theme will not be compatible with www.ads-software.com language packs.
The domains found are resumy,

But as you can see, only one domain is visible.

How can I have more information, so I know where to edit the wrong line?

Thank you very much!!!

S.
