Issue with translation and localization…

Hello. I had problems for translate your plugin. I was trying in the on-line system and with POedit, but didn’t work. Could you please check?

This is the message I have:

“This plugin is not properly prepared for localization. If you would like to translate this plugin, please contact the author.”
