I have uploaded a new docx and pdf through the media library and the procedure is completed successfully. I can confirm that the direct link actually works.
The problem is being identified when I try to DELETE PERMANENTLY the files.
By clicking on "Delete Permanently", the file record is deleted from the media library, nevertheless the actual file (and its direct link) still resides on disk. On the other hand, Wordpress returns a message that the deletion was completed successfully.
Can you suggest me possible steps to debug the above-mentioned prcedure?
Wordpress 4.7.3 currently resides on IIS 8, with PHP 7.0.x. I have checked some possible user permissions for IUSR, and currently on files is being given full control.
Thank you, Chris
