I have a very serious problem with variable administration in a multi-user project. I don't use VPN to connect with multiuser server, I'm in the same network.

When I click: exclusive access to the entire variable administration, I take control of all variables but at the end clicking "Accept changes" I get this error: "An error occurred while checking in elements". Restart of editor doesn't help, the only thing that works is removing from local.ini file: "[MU_MODULE] VARIABLES=2" and after doing it I can discard changes (and lost all new added elements) but still can't accept changes. It means that I'm not able to work via zenon because all the changes don't save.

Do you have any idea how I could solve this problem?

Thanks in advance for your help!
