I have a problem that some file is geting locked and not the owner nor admin can unlock it. The only thing that helps is restarting alfresco which is obviously a bad thing to do during the working hours.
It doesn't matter which way the file is editing, online or offline, for offline editing button cancel editing just does nothing, no error messages are shown, nothing.
What can it be and how to solve it?
Alfresco version is 5.0.d by the way.
