We were using a very old version of phpList. Perhaps the chief reason for using phpList is that it enabled us to send the same email every day to the whole list. (The emails contained links to places on a website which changed each time a person visited them, so that they read the next item in the series.)
This behavior seems to be blocked in the current version of phpList.
What can I do to work around this blocking in order to achieve what we originally chose phpList for.
@drmikegreen You are probably referring to the “repeat” functionality, where phplist automatically creates a new campaign with the same content etc. That is disabled in phplist by default but can be enabled. See config_extended.php for an explanation of USE_REPETITION then copy the setting to the config.php file.
