Hi, I still facing the same issue. and it is urgent to solved.
regarding error "An error has occurred on the server and has been logged".
Everytime people updating the activity, it will automatically logout. and I noticed that when people use direct cable, will not get this issue. But if people use wifi, they will get this issue. it like need to use strong connection. I'm using shared database (Version 21.0.295.0, Update 9) and will be accessing from others branch offices in Malaysia and others countries. and they all facing this issue.
