I use Libre Office community 7.3.2.2 on a MacBook Pro (before M1) with MacOS 10.15.7. My Fritz.box is the model 7560.
Libre Office (LO) crashes quite often and i get a message that says: “Either another instance of Libre Office is accessing your personal settings or your personal settings are locked. Simultaneous access can lead to inconsistencies in your personal settings. Before continuing, you should make sure user “xyz” closes LO on host “xyzMBP.fritz.box”. Do you really want to continue?”
Where should i try to solve the problem? Is it coming from the MacOS? Can i change settings within LO? Or should i change settings of the fritz.box?
I don’t remember having set up anything that connects LO with the fritz.box. And of course there is only one computer. There are not two or more instances of LO open, only one instance.
