I created an application in php that uploads files (PDF, images and JSON) that works correctly on my PHP 5.2.17 server, but on the client server, the application only works if I change the permission of the site folder to 777.
On my server I use 755 for the folders and 644 for the files and everything works correctly, there are no errors in the application on my server, I use move upload to load the files.
Does anyone have clues to what might be happening?
