Hi, I upgraded and rebooted the Manjaro to find my toolbar was missing. I tried to find solutions on this and other forums. However, I’m still stuck. Here is some information that may come handy:
This is my first post on forum, kindly bear with me, if there are any missing details.

Some common errors…
However, I don’t know what you mean by ‘toolbar was missing’.
Do you mean your panel?
Can you see a wallpaper? Right click and try to select ‘add panel’
Can you create a test user and get a default desktop? This would mean it’s an error in your /home directory and config files (most likely).
This is an error completely on my end. Selecting ‘add panel’ default worked. Also, I’ll keep in mind to add backticks if I find new issues. Thank you. 
Closing the post.
Hi @auspicrypt, and welcome!
I’m presuming by “toolbar” you mean what is called in Windows the “taskbar”. If so, you should know that in Linux, so KDE, Gnome and others, it’s called a panel. And it can hold many things.
Like a menu (Application launcher), a clock, and/or a system tray. These are called widgets, and they are customizable.
If it dissapeared, open “System settings” and look in the appearance section. Enable and customize your panels to heart’s content.
Hope this helps.
