1. First of all we should open a file, specified in the warning message. Please, check the screenshot above. You will see path to file there. Download the file and open it with text editor. In our case issue is related to the code, specified on line 64 (please, refer to the screenshot above). Open the appropriate line of code. In our case the issue is related to text_wishlist constant.

   

2. Check a code above this line. We can see the reference to language files inside common folder.

   

3. Go to a catalog/language folder and open the folder with the appropriate language pack. In our case the issue appears when we select Dutch. Path to file is catalog/language/dutch/common/header.php in our case (as common/header path was specified in the header.php file we have checked initially). Open file with the editor. We can see text_wishlist variable. In our case this variable was specified in system\modification\catalog\controller\common\header.php on line 64 (the file we have checked initially).
