XFCE cannot put any launcher on panel

The XFCE is from Manjaro Arch Linux OS installed with minim installation
but then after doing some files operation on ~ dir., cannot put a launcher on panel (never done once before doing around ~ dir. to ensure it can or cannot put it)

How to fix it?
Some inadequate permission on a file? Please help out !

Re: XFCE cannot put any launcher on panel

Make sure you own all of the files in your home directory (and subdirectories).

What does the following return;

ls -l ~/.config/xfce4

...and:

ls -l ~/.config/xfce4/xfconf/xfce-perchannel-xml/

...and:

Re: XFCE cannot put any launcher on panel

I suspect failure before the all Xfce panel setting saving as try to put launcher (any way menu in whisker or drag-drop) then quickly test with
find ~/.config/xfce4  -mmin -1

i.e: get a modified one under that dir, less 1 minute ago

with nothing found at all and a first most is sudo chmod -R 777 ~/.config/xfce4


Any brighter idea where should be the fault ?

Re: XFCE cannot put any launcher on panel

Restart your computer and before logging in, go to a virtual console, Ctrl+Alt+F2 and run the following commands:

sudo chown -R budi:budi ~/.config/xfce4
cd ~/.cache
rm -rf sessions
sudo reboot

See if that helps.

Re: XFCE cannot put any launcher on panel

Lets get an xfce4-panel debug log. In a terminal window run this:

xfce4-panel -q
PANEL_DEBUG=1 xfce4-panel

When the panel loads, try adding a launcher. Post back all the output on the terminal window.

Is this a fresh Manjaro install using Xfce from the default repo? Have you tried manually building xfce4-panel or any of its components?

What do the following commands return:

locate liblauncher.so
pacman -Qi xfce4-panel
ldd $(locate liblauncher.so | grep xfce)

Can you explain the steps you take to put a launcher on the panel?

Also, try creating a second account on your computer to see if it works there.
