I tought my installation was corrupted so I deleted everything and did a clean new installation but still got the same problem. I tried to input .xml , .zip , anything I input give me this kind of error... Anyone can help ?

well, by looking at your server path, why in the world are you using UPPERCASE Letters, and what is
the reason for using so many directories, like clickandbuilds/OpenCart/MyeCommerce/ ?

Are you trying to do a QUICK Install, by use of a server-sited pre-installed Opencart Software ?

Hi Ernie, thanks for your reply... yes I am doing server-sited pre-installed Opencart on a 1and1 hosting. All folders are created with this name by default. If you think this could cause the problem I will be changing them tonight just to make sure. If you have any other suggestion let me know...

Thanks !

Hi, I tried to rename folders with lowercases character but if I am changing anything I cannot access the admin panel anymore. Any other suggestions ?

Thanks !
