You are right – not the environment – no difference. Changed the PW for your test account – same results…changed admin PW – no difference…Changed user levels (editor – subscriber etc….don’t think that matters in buddypress but…) nothing…Deleted BP-Custom file…Thought my IP address may be an issue…so I deactivated mediapress and activated rtmedia – previews and uploads work fine with rtmedia !
Very strange…I see your image posted – but I still cannot get it to work without error !
As far as Activity Plus – Honestly – some of the users like embedding a url -link and video- and formatting a link with a thumbnail etc…very easy for them !
I am going to restyle the links and make the mediapress activity buttons stand out more as they are the primary resource for media.
The only thing I have changed is on my Linux system – I updated Firefox and Chrome…guess I have to fire up the windows box and give it a go. I can’t think of any other reason this shouldn’t work !
I very much appreciate your time –
