We have just upgraded DMM and VPT from 5.1 to 5.2 with Show & Share. (DMM 184.108.40.206, SnS 220.127.116.11 )
The DMM and Signage is working okay, but the Show and Share portal is having some issues.
When we go to upload a Video in My Show and Share, you add the description to the Item and browse to the file then we see a sign in problem as we press "save to Draft" or "Prepare to Publish". the error is attached in the screen shot SnS Failed Upload, and SNS SHowing we are logged in.
We have changed the Portal so it is pointing at its self to publish the files locally to rule out our Streaming Media Servers ( Windows media and an Apache Server) but are still getting the same errors.
