SMTP authentication not functioning for email notifications

I did recently mention in the thread about the debug thread I created, that despite set to ‘0’ debug logs are still being generated even with the newest code.

The only two errors I am seeing are:

ERROR - 2023-08-25 00:00:34 --> Severity: Notice  --> Undefined index: billseconds /opt/ASTPP/web_interface/astpp/application/models/common_model.php 204
ERROR - 2023-08-25 00:00:34 --> Severity: Notice  --> Trying to access array offset on value of type bool /opt/ASTPP/web_interface/astpp/application/libraries/Usertracking.php 224
