  • Hi there mate,

    the message saying mail wasn’t sent (un-luckily) takes tha last PHP error ,and prints it, thinking it’s the message from SMTP server why message wasn’t sent.

    SO the problem insnt “undefinied index”, it’s from another plugin, there is aproblem with your provider.

    1. Are you on local host?
    2. Do you have any e-mail limits? Per day / per hour?
    3. Do you need to setup special outgoing e-mail address?

    I am also getting the error code: Undefined index: themeZee_fonts_activate.

    I actually see the subscriber’s email address, back in the WordPress admin Subscriber section, even getting this error.

    Any clues as to what is happening?
