Libre Office won't open

Anything LibreOffice will not open.

I can open it if I switch user to guest.

I have searched and gotten many results for this problem, so that it seems to be common, but the answers are unintelligible to me. This one here said:

...there is a hidden folder ~/.config (so in your home directory). Could you make >it visible by typing Ctrl+H while in your home directory and remove the libreoffice >folder inside that folder? Good chance that all works fine then. Possibly (probably, my >guess) some settings file is damaged. Those files are not removed when uninstalling I >believe. – Jacob Vlijm 2 days ago

I don't know HOW to do this. Could someone please take it the very beginning, for someone like me who doesn't just know this stuff? Again, it seems like a common problem with an easy fix, if I just knew HOW.

i'm not going to add anything to Jacob comment but just inserting some screenshots to help:

Open your file manager and go to your home(it will open there by default).

Show hidden file by pressing CTRL+h

Now you can find many hidden files/dirs search for that named .config

Now open that directory and search for directory called libreoffice

Now remove this dir by pressing Delete or rightclick --> Move to Trash

Now log out and log in again then try to open libroffice again

An additionally answer using terminal way:

Open a terminal with CtrlAltT and fire this command:

rm -r ~/.config/libreoffice

This command deletes the folder .config/libreoffice in your home folder ~, but not the folde .config itself ;)

Alternatively you could create a backup of the folder with:

mv ~/.config/libreoffice ~/.config/libreoffice_bak
