I am getting a conflict between Yuzo related posts and any plugin that uses wp_mail for example mandrill. And this is with only the yuzo and the mandrill plugins active on the site and default theme. This is the error message:
Mandrill: wp_mail has been declared by another process or plugin, so you won’t be able to use Mandrill until the problem is solved.
Hello, it is strange what is happening but that message is from Mandrill.
They have to give you a reason why that message is sent and with that reason I can review within Yuzo if something is happening.
