Mirror site and error while installing

[Alexenn]

Hello,

 

I am trying to install a mirror site in a subfolder from my root, I saw some answers on this forum on how to do that, so basically I've transfered every files/folders in my /mirror/ subfolder, and then I add an "install" folder like it's recommended on this thread : https://www.prestashop.com/forums/topic/262734-solved-creating-a-dev-site-from-a-live-site/

 

The problem is while i try to begin installation, during the compability system check, the installer tell me than "All files are not successfuly uploaded on your server"

 

So what should I do from here in order to make it works ?

 

Thanks

I just had to delete the cache folder and copy the original one coming with the installer.
