I have tried to uppgrade wftpserver from 4.4.1 to 4.5.6 Linux 64 bit on Ubuntu 14.04.1.
Everything runs ok, version and licens looks ok too. But I can not change any config from webb GUI. No system settings, not add users or group, not change password or IP-filters. When i click ok it looks normal but when i go back into config the last change is gone.
I got no messages about it in any log or in GUI. I have tried on both our servers with same result.
When i go back in revision to 4.4.1 it works ok again.
Is there any known bug or any new library needed? I am stucked.
