We have just upgraded our Support site from 3.8.1 to 5.3. One of our threads is a Charge batch that is downloaded one time per day. The 5.3 version is failing to process the file, but the old 3.8.1 site is able to recognize and process the same batch file we are trying to send through 5.3. We have checked the thread configurations and they match. Is there some difference in the way 5.3 handles batch files? Any ideas on why 5.3 would not be able to trace a path to these files?
