ColdFusion Adminstrator 2023 "Failed to add HTML header"

ColdFusion Adminstrator 2023 returns a "Failed to add HTML header" error when I try "Export Server State" in the Package Manager.  This happened on Update 14 and continues to happen after Update 15.

 

I made sure (from another thread referring to this error) that "Disable updating ColdFusion internal cookies using ColdFusion tags/functions" under Memory Variables is unchecked as suggested.

 

Any suggestions?

The problem is not yours. It's a bug in cf, and coincidentally I had reported it last week at the Adobe bug tracker. I hope you'll add a vote, as they give heed to that. This way also, you would be notified if/when they resolve it.
