Translation problem

[David763]

Hi,

We are using the classic News theme in french (we customed it).
We translated the po file with Poedit.
We have some troubleshootings :

1- in the HP, the string "[Read the full story]" appears and we can not find it in the po file.
2- in the po file, we can not find the string related to the "eNews & Updates" section (also it exists in the po file for the magazine theme for instance). How can we change it ?
3- the search box : when we translate the string "Search for" in the po file, nothing appends in the search box section. Do you know where we can find the string to change it ?

Here is the url : www.compas-moyen-orient.com

Many thanks in advance
Regards
David
