I am having trouble with my Wordpress site and I posted this question on the Wordpress support forum a week ago but have got no responses, so I hope I have better luck here as I really need a solution.
I've built a WordPress website in English and now I need to change it all to french, so I did some searching and followed the steps to change the language in the wp-config file (using the .mo file), and for the most part it worked well, except that some parts of the website were left in English. For instance, the search results page. If you search for something and it finds nothing, the whole "Nothing found" message is in English. The 404 page is also still English, along with a few other small areas around the website.
How do I go about getting these areas translated like the rest?
I'm using a Twenty-Thirteen child theme and Wordpress 3.7.1 if that helps, and I have not modified the areas that didn't get translated.
Thanks in advance.
