Localization + Thumbnails for Products

Hi there !

Since the last update of global site search plugins I have some problems.

I follow this topic https://premium.wpmudev.org/forums/topic/global-product-search-with-thumbnails-solved
to have Thumbnails for Products (with Marketpress)

and this topic https://premium.wpmudev.org/forums/topic/localization-does-not-work
to make work the plugin's translation.

But since the update, the code have change. Unfortunately, translation still not working without modification.

Moreover, I tried some modification to have Products Thumbnails, but nothing works.

Can you help me ?
