Thank you very much, it worked. There was no permission set for the Plex or Admin user. Any idea how the upgrade get control of DMS to change the permissions?

So has this been a problem with previous Plex versions? Was it all under this version of DSM or others? I have installed all the previous Plex and DSM versions and this is the 1st problem I have run into.

Thanks again for your quick response

I wanted this to be released before 1.15.4 went out. That was out of my hands.

Here is my release announcement . Please feel free to ask if there are any questions.

Your addressing this to the wrong person, my problem was solved with the 1st reply.
