ExPack: Error messages for "ScanBagFrame; ShowExPack false...when I open the mail box

I keep getting ExPack error messages when I open the mail box in game. It seems related to a bag frame…but I am using only Bliz’s basic ingame UI bag frames.

Not sure why this started happening today. Was not a problem Friday but today, I’m getting this error spam consistently in my chat box every time I open the mail box regardless of whether or not I actually have mail.

I can’t add a screen shot in this post box, so I no idea how I can show what I’m getting. If there’s a way to copy a screen shot into this area, please let me know.

This is basically what its reporting:
ExPack: 630152.003 [WARN] ScanBagFrame; ShowExPack false; 210408 3 0
ExPack: [WARN] ScanBagFram; ShowExPack false; 210407 2 0
…and it continues but I can’t copy the text out of the chat box in order to paste it here.
The last line in all that spam is: ExPack: [WARN] ExPack_SendMailFrame_Update; filtersShowSendMailAttachments; false

Is there a way to copy text out of the chat box? If so please let me know and when it happens again, I’ll see if I can accomplish that to provide every single line item mentioned because it goes on and on an one with the only differences being the last digits of each line.

My hunter is also getting this and all she did was check her mail. Have no idea what’s causing it.
