I upgraded 2 boxes from 16.10 to 17.04. All of the shortcuts to file directories that I added on my vertical panel have disappeared. I cannot add them back. I cannot seem to add anything at all to my panels now either through the panel, or by dragging an icon onto it.
Are there settings that I am missing somewhere?
[quote=“Calis, post:1, topic:12995”]Are there settings that I am missing somewhere?[/quote]Have a look in:
Control Panel -> MATE Tweak
and
Control Panel -> Windows
Personally, I would suggest simply forcing the issue and switching back and forth between several panel layouts in MATE Tweak. What probably happened is that between 16.10 and 17.04 something crucial changed in the panel layout you were using. Switching back and forth might jostle something.
Well, I tried that without thinking about it much. I lost everything that I had customized and it all went back to stock, and I still can’t add anything to my left panel 
Can you add items to a newly created panel?
Nope. I tried to add a new panel and add things to it, no dice.
Sounds like a bug to me then.
Maybe you should create a bug report?
hey- i am curious, is your computer has newer intel 7th generation? is it PC, not laptop, correct?

How to go from there, not sure. Something might’ve broken in the upgrade. All I have at this time is the suggestion to simply go with a fresh install of 17.04. Sometimes upgrades just break stuff. It happens.
Definitely report it as a bug though.
