Previously I had configured Pro Reports only to send the email and NOT attach a PDF. This has been working flawlessly until when the most recent reports went out on 3/1 and now they all had a PDF attached. I believe there was recently an update to the Pro Reports plugin and I’m wondering if that’s what caused this. Unfortunately, I don’t remember how I made this happen.
Do you remember if you inserted it using the Custom Dashboard extension, or perhaps directly in the functions.php file of the Dashboard site’s theme?
Please see if the code is in either of these places.
