Phpinfo: file upload on, Max file size 128M. uploads folder is empty, it's in the root directory where the script is located, no errors are displayed and nothing seems wrong with the script

So you kinda need to get to the folder you are trying to access. I had the same problem i think a while back. The solution i found was doing this with the $targetpath:

You need to get the webserver path, in order to do this you use the dirname(__FILE__) function. Depending on how far you are going to go in the file path. Forexample i needed to access a folder "nydemo1/bilder/images/folders/" then i needed this for my filepath variable:

dirname(dirname(dirname(__FILE__)) //because this is 3 folders deep

Hope this helps
