Front end labels of Appointment+ in French


this is Stephane again from Paris France.

I installed Appointments+ on the following site :

I would like to translate all the front end labels in French since this is for French clients.

I started to edit the default.po language file in /wp-content/plugins/appointments/languages and uploaded in the directory my edited fr_FR.po and files.

However, for the fields/labels that I have already translated, I cannot see any difference, all the labels are stil in English.

In my wp-config.php file I have set :

define(‘WPLANG’, ‘fr_FR’:wink:;

What am I missing or doing wrong?

Thank you for your help to tell me what i need to do to have the front end labels translated in French for Appointments+.
