Multiple notification emails

Same issue on our website.

Possible conflict with other plugins. Is this “post” or other custom post type?

Nothing customised, just a trigger for “post sent for review”.

Ok, are you maybe using the Pods plugin?

I am using it

It looks like this might be related to an issue another person reported with Pods and Notifications:

No, I’m not using the Pods plugin.

It’s a quite hard bug to trace down, to be honest. Maybe, but just maybe, some plugin is looping over the post update action, but I’m not sure.

I need to take a closer look at this as this bug come back once in a while.

Good news! I seem to resolve this issue and the patch will be released very soon!
