I am using the s2member-pro plugin to subscribe users to my website as a paid service and I am also using a plugin called subscribe2 which sends out daily emails of all the new posts. In the subscribe2 plugin, they have an option to auto-subscribe new users which I have enabled; however, it is not auto-subscribing new users.
I spoke with the developer of the plugin and he said that he did a quick look through of the s2member code and he said that the 'user_register' hook is never fired when users are created via the plugin on non-multisite configurations of WordPress and the comments in the code says that you are considering alternative ways of registering users through the WordPress API.
Is there any fixes that you might be able to recommend that I can try out to get this working?
Thanks!
