I just installed LibreOffice 5 on my MacBook Air. When I tried opening a very recent file (from today), I received an error message that says
"Either another instance of LibreOffice 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 ‘thomasnalesnik’ closes LibreOffice on host ‘Thomass-MacBook-Air-3.local’.
Do you really want to continue?"
This sounds similar to a situation another user was experiencing with a phantom version. How can I close this other LibreOffice? And where is it? Or how do I unlock my personal settings?
