On the subscriptions issue I did actually subscribe to three threads yesterday morning to see if anything happened in terms of email. Sadly none of those three threads has since had a new post so I am still waiting on that. If you want to make a new post to test this out then i am subscribed to the topics ‘Willy Weasals Nap of the Day’, ‘Introduce yourself’ and ‘Trainer trend of the day’.
But – as I believe we have said above – emails are the province of WordPress. Simple:Press emails are simply sent to the WordPress email system and if they are not being sent it is this that needs to be looked at. Simple:Press is a WordPress plugin that uses WP core code and routines.
On the permission front the best and easiest way really is to grant us SP admin capabilities so we can look at your data setup closely to see if we can see any issue. Access control of this nature is working just fine for all our other users including for us on this site and while I would be stupid to rule out a possible bug in the system these things more usually come down to the setup.
