Diagnosing BNFW not overriding Comment notification

I understand that our first line of triage is to follow the best support doc. Note in that doc that the recommended Email Log plugin is obsolete. The link to that plugin also has an extra leading period.

The issue I’m trying to diagnose is that the Test from the email to Comment Author is working from a Test, but it’s not being triggered with an actual Comment.

Deactivating all plugins for any site is undesirable and not practical, though yes, it’s effective and widely the most cited first line in issue diagnosis. To diagnose this issue, I’d like to know exactly where in the process that you hook this specific notification. A link to source would be welcome and I’ll track it down from there.Or if this is a known issue, please let me know.

If there is a better way to track this and similar issues with code, please let me know. I have code that looks at the list of filter/actions to determine if and when specific plugin hooks are present – and sometimes I use that to remove the filter. If you can tell me the name of your hook, I’ll look to see if something else overrides that and I’ll report back here.

Thanks
