Hi Claudio,
Thanks for your prompt reply.
I receive e-mails from WordPress so that seems to work.
I have send e-mails to another address (not related to the domain of my site).
When I copy the link and open this in another browser it works fine.
After I select some photos and send these back I don’t receive a notification by mail but I can see within Picu that it is approved and see which photos are selected.
Just sent you the Debug Info by mail.
Thanks a lot.
BR,
Chris
