[Prestashop] Debug 1 module

Hello, BEWARE: YOU MUST WORK ON WINDOWS, NOT MAC. YOU MUST BE A PRESTASHOP SPECIALIST !! --------------------------------------------------------------------------------------- MODULE DEBUG I have bought a Prestashop module on Addons. The problem is that this module doesn't work and crash my PS when I install and run it in local (with Xampp). This module installs /override/classes/module/[login to view URL] After installation, when I try to access the modules page in BO, I get this error message: [PrestaShop] Fatal error in module file :D:\xampp\htdocs\prestashop16014\override\classes\module\[login to view URL]: Uncaught exception 'Exception' with message 'Error D:/xampp/htdocs/prestashop16014 is different from D:xampphtdocsprestashop16014' in D:\xampp\htdocs\prestashop16014\override\classes\module\[login to view URL] As you see, there is a slash problem. Sometimes they are slash, sometimes anti-slash and sometimes they disappear. The developper of module cannot help, as he works on MAC and it is probably a Windows/Xampp specific problem. Your job: - debug this module and have it work perfectly in local as well as online, and be sure it works for PS 1.5 and 1.6 (I have both versions). - As this module alter the PS override process, you must make some tests by intalling this module and some other modules after that (modules that install overrides), in order to check if this module works fine.
