Please, always start a new thread for new problems. Otherwise we'll get a mixup and cases are hard to handle this way.

And please provide your server's error log to give us an idea what's going wrong.

hi
Arsalan Shah

@David,

I found a bug on your server, the issue is when you upload files using ftp the owner of files is ftp, when Ossn or any php script tries to generate file a www-data user is assigned to it, and your www-data user didn't have permission to delete files.

Your dynamic generated php scripts must have read/write/delete permission for Ossn to work correctly.
