What does this error mean?

[Matthew_Morgan]

We have a customization on Receipt Entry that includes custom EpiButtons to send a PO to various printers in different locations depending on which one is clicked. This past weekend, we upgraded from Epicor 10 to Kinetic. Just now, when attempting to print a PO from the custom buttons, this error occurs, and nothing prints.

What does it refer to?

Is the customization writing a file?

Anything else change? On new servers? Using Terminal Services/Remote Desktops?

Do you need to clear out your temp files?

Problem resolved - we just had to restart the Bartender integrations. Thanks for all the responses.
