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.remarpro.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.
