I'm facing a really simple issue : We made a theme for a multisite wordpress (see here : http://www.agence-malttt.fr/) and translated it with Loco Translate for French.
It's still showing English version (hardcoded one with _e() ).
My theme now has fr_FR.po and fr_FR.mo, like it was all the time.
The problem is the translation doesn't apply whatever i'm doing. I've even made changes to wp-config.php and added define('WP_LANG','fr_FR'), changed in general settings and changed in Multisite feature for WP_LANG to be fr_FR too. Still doesn't do the job.
Can someone help us? What did I miss?
