  1. You could :
    1. Manually copy the files  (cf. Manuel Configurateur Visuel , Paragraphe "Installation") via some FTP client
    2. OR, just make all directories mentionned in the documentation writtable by the server Manuel Configurateur Visuel, Paragraphe "Installation"
  2. Re-install the module

Error- " Cannot delete (...) "

...

  1. You could:

    1. turn off the "devel mode" ( file config/defines.inc.php ):

      Code Block
      define('_PS_MODE_DEV_', false)

    2. AND/OR (since Prestashop 1.5.3.1), fix the Prestashop's core on ImageManager class ( ImageManager.php)
