If it is only libreoffice with a problem, you may want to look at trying libreoffice in 'safe-mode'.  If you can create and save documents in safe-mode then it implies there might be a problem with your libreoffice user profile.

In a libreoffice window click 'Help' then 'Restart in Safe Mode...' then 'Continue in Safe Mode'
OR in a terminal window type

Code:

libreoffice --safe-mode

and select 'Continue in Safe Mode'

This should open libreoffice with a fresh, temporary user profile which will allow you to try the functions.
