Can you try using the same syntax for logging that is used in the rest of the file (I am not sure this makes a difference, though)
LoggerManager::getLogger()->fatal('Message');
Are you using a debugger, can you set a breakpoint there?
Maybe there is more than one place generating meeting notification emails and you are changing the wrong one… if the code execution doesn’t run through your changes, that must be it…
The initial meeting invite which we get after the meeting is saved with option “Save and send invitees” uses the variables from modules/Meeting.php
But the reminder emails are using the variables from modules/Activities/EmailReminder.php
we need to define the same variables at setReminderBody function something as below.
