[Plugin: SimpleModal Contact Form (SMCF)] Having trouble with po/mo translations

Hi,

I have the version 1.2.6, and I’ve my po/mo files from here : https://www.ericmmartin.com/projects/smcf/

I put these files in /wp-content/plugins/simplemodal-contact-form-smcf/lang/

But nothing appear, all texts are always in english…

Have you an idea ?
