I just changed the specifications on uploading files. I set it the file limit to 100MB (highest file i have is 60 MB). When i try to upload the file, it gets to 100% then gives me an error that says "There was a problem uploading your file." I also added the extension .exe, so I shouldn't have a problem. I don't understand whats wrong? I even tried it with a 10MB file, still experiencing the same error. However, the 3MB file worked.
You can only access /etc as root. If you are on a dedicated or VPS server then you should have root access. For other types of servers like shared servers you don't get that level of access and cannot edit the PHP configuration.
