Oh you guys are good!
I updated from the /upgrade page as suggested, and .. like magic, the upgrade ran efficiently to completion and all was put to right.
With the ‘email total attachment size limit kb’ value still set to 0, I verified successful outbound notifications (including those that had been in the queue)
I then set the ‘email total attachment size limit kb’ value to 10 MB and verified successful outbound notifications include attachments as expected.
This bug appears squashed.
Thank you very much for all your hard work on Discourse and for the prompt replies! It is very much appreciated.
