Hi Alex
I may have solved the problem after all.
I have had a lot of difficulty finding my way around Komento. It is obviously a well-regarded and powerful program.
However for a newbie like me, looking at this sort of extension for the first time, it has been a rocky road of trial and error finding out how to choose the many settings.
I did not understand that I did not need to choose any notification recipients, because I did not understand what a content author or a subscriber was.
Choosing to activate “Notify content author” and setting up a special User called “Comments” caused the most recent blip. Since I have deactivated “Live Notifications” and disabled that User, the problem seems to have disappeared.
The help tips (?) did not help mel – they did not define the term, but merely repeated it. It would have been useful if there had been a general description of how the program worked, and then some sort of glossary of each of the technical terms.
I think the program will be of great use to me, so I will keep working on getting a better understanding of it.
Regards
Grahame
