Analytics Software

Hi all,
Recently we initialized Workforce and since then we have seen quite some problems. Until then Planning was very stable, but from the moment we initialized Workforce that stability went down the drain. Unbelievable how different it all is now...

Currently we keep on getting the following message when we want to make a change (any change, however simple) in a form:
You are trying to change data that has been changed by a user on another server. Wait a few seconds and try again. If you continue to see this error message, please contact your administrator."
Even if we wait for an entire day, we still get the message. Actually, we get the message even if we try to edit a form which has not been edited since starting Workforce.

So, our basic question is: what does this error message mean? We can't find this message in the documentation and it doesn't show a error number either, so it is difficult to search for it.
