FosuserBundle ( The path "fos_user.from_email.address" cannot contain an empty value, but got null. )
The problem is with your parameters.yml file:
parameters: ... mailer_user: null mailer_password: null
Change that to something then you won't get the error.
The FOSUserBundle has built-in support for sending emails in two different instances.
These values cannot be null, so if you try to set the value of these properties either with "" or ~, the problem will persist.Give values other than null. It will work.
