Yes, we do have the Cache-Mode set to 1 in our ar.conf file. Also, thanks for the hint on the arthread.log file. I guess when I change the Cache-Mode in our ar.conf i'll also add the Copy-Cache-Logging command in there as well.
By setting this value to 0, would workflow changes essentially behave same then?
