I upgraded to the latest (4.0.4) and can't seem to find how to send a Private Message to another user. I have 'Conversations' enabled but I don't see how to send a message anywhere on the front-end. On version 3 there was a 'PM' icon next to a user.
I was just debugging another site and it looks like there is a bug with our "setup". It should set the "PM" to be enabled by default but it looks like it has always been disabled by default.
To change this, go to the ACL section of EasyBlog and enable the private messaging for each of the user groups that you want to allow.
