CFFTP - PutFile Action results in SAXParser error after upgrade

I had some CFFTP code action=“PutFile” working to push an image to another server. It was working great.

Then, I upgraded to 5.3.2.77.

Image is no longer being pushed to other server. Now I get this error, when running the same code:

java.lang.RuntimeException | problem initializing SAXParser pool

Is there another update that I need to run? Does anybody have a workaround for this? Thanks.
