i have an application that can also upload files in a folder with permissions 777. it was working until i deleted some users from the server's usergroup psacln. So this post is not actually about a problem with php, but about a problem with linux and apache.
I have many domains that are using the application and they all have problems when uploading files. The folder upload that i'm using for uploading, has domain_client as the owner, and psacln as the group. I've probably removed something from that group that was used for giving access to them...
I really need some help with this as is urgent! Thanks!
