I'm currently running a v17 engine on a Virtual Private Server with Ubuntu LTS 17.04 / PHP 7 and am experiencing an issue when trying to attach files or insert pictures into an article. This is a feature I had never tried before, as we just injected text into the wiki to create a maintenance knowledge base.
Settings: tiki is configured to store files/pictures into a directory. I've selected a secondary disk which I subscribed with the VPS; the 2nd drive is mounted as /media/diskext and I created the following folders: /media/diskext/tw/galleries/ and /media/diskext/tw/attachments/ to host the files.
Uploading seems to go through, but when I try to read the uploaded file, I always get an error "Unable to access file: /media/diskext/tw/galleries/xxxxx".
I suspect a permission issue but don't know how to troubleshoot this. I have full root access to the VPS if needed.
Thanks in advance for any help!
