I cannot change the font color in calc

Dear all,
I am using LibreOffice 6.1.3.2 on Debian 9.6 (stretch-backport).

I cannot change the font color.
(Note: Meanwhile I am writing in a cell I can see the color that I selected, but when I press enter the text go back to black color)
Tools > Options … > Accessibility > “Use automatic font color for screen display” is unchecked.

I don’t know what I am doing wrong.

Thanks on advance for your support.


Update (01 Dec 2018):
The issue is resolved after deleting folder /home//.config/libreoffice.
Thanks ebot and CLSC for your support.


Can this help? [question/49513/]

Have you tried selecting all the characters in a cell and then changing the font color from the toolbar icon?

I tried to do it selecting all cell.
I also tried to do it selecting all characters within the cell.
Both actions didn’t work.

Note: I have the same issue in the last version LibreOffice on Debian Stretch (9.6 x86-64) without using stretch-backport. I don’t remember exactly the version 5.x

Thanks on advance for your suppport.
