Unable to load a theme

[amedeomantica]

Hi all, neither via automatic way (upload via webpage), neither by manual copy then installation vie web, I'm able to install a new theme. I get the green notification, Upload succesfull but the theme won't show up in the themes page.

 

Looking at logs I found this:

 

PHP Warning:  Invalid argument supplied for foreach() in ...path_to_the_shop.../shop/controllers/admin/AdminThemesController.php on line 1536, referer: _urlPath_/shop/adminwhatever/index.php?controller=AdminThemes&action=importtheme&token=whatever 

 

Do u have any idea ?

Thank you
