I am newbie with the newsletter plugin, trying to run it on my website. Everything seems to be OK, but while I’ve put the registration form on my site, there’s appeared the notice: “Notice: Undefined index: lists_empty_label in (…)/ftp/wp-content/plugins/newsletter/widget/standard.php on line 35”
What I’ve done wrong? What to do? Help, please… :-(((
This error can be avoided with the help of PHP isset(). N.B. Undefined index is a minor error and is, therefore, not usually notified by default are two special PHP functions that are used to get variables from a user-filled form. MYBKExperience
