comment
-----
The steps above are what I was doing before the crash occured. And May not produce the same results.

However, XFCE is no longer starting up as normal, Terminal has to be used typing "xfce-panel" to start program.

below is what is shown when startxfce4 is run

[name of user~]$ startxfce4
/usr/bin/startxfce4: X server already running on display :0.0
<stdin>:1: error: Unknown #directive "Those"
    # Those are fallback settings, use the ui plugin to change it
<stdin>:2: error: Unknown #directive "or"
    # or add your overrides to ~/.Xresources
<stdin>:3: error: Unknown #directive "Xft"
    # Xft.hintstyle: hintnone/hintslight/hintmedium/hintfull
<stdin>:4: error: Unknown #directive "Xft"
    # Xft hinting: 1/0
4 errors in preprocessor.
xrdb:  "Xft.hinting" on line 9 overrides entry on line 6
xrdb:  "Xft.hintstyle" on line 11 overrides entry on line 7
