XFCE panel dissapeared after restore in 18.04

Please run the following terminal command, and then try reproduce the problem:

killall xfce4-panel; xfce4-panel

I reproduced it very easily and the problem is that I don't have any panel at all now, even after restart :((, it's really not pleasant, I hope I don't have to reinstall the linux.

See attached video, I recorded the problem.

I really don't understand why this bug has the status "Incomplete" although I provided all the necessary info and also broke my xfce panel...

Thanks for the quick reply.

The terminal output which is partially visible in your video may help to debug this issue. Please attach it to this bug report.

Now I don't have the possibility to reproduce because I don't have a panel at all (to import), as I mentioned in the last post...:(
How can I make it appear again?

What terminal output do you get when trying to start xfce4-panel?

Other than that, you can restore the default configuration by removing the following files:

~/.config/xfce4/panel/
~/.config/xfce4/xfconf/xfce-perchannel-xml/xfce4-panel.xml

When I write "xfce4-panel" in the cmdline, I get nothing, the terminal is stuck. When I press Ctr+C, I get this.

taw@taw-pc2:~/Desktop$ xfce4-panel
^C
(xfce4-panel:1776): xfce4-panel-CRITICAL **: 20:38:24.593: panel-application.c:1250 (panel_application_save): expression 'XFCONF_IS_CHANNEL (channel)' failed.

I will try to reproduce this bug with your config file.

Were you able to restore the default panel configuration? Alternatively, you should be able to run "xfpanel-switch", and pick a preset.

I was able to make your configuration work by removing these two lines from the config.txt:

/panels/panel-1/output-name 'monitor-1'
/panels/panel-1/position 'p=8;x=94;y=1019'

Great, it works also on my PC now.
When I exported it, I had a different PC with 2 monitors and bigger resolution.
Could this be the problem?
