Hi Dia, forget permissions, this one is about promoted actions.
The button you are trying to show is only a copy. The real action sits somewhere in Actions, Related or Reports, and if that one is hidden, the copy can't come back. That's all the message is saying, just badly.
So look through those menus in personalisation, find the same action hidden there, show it, then go back to the promoted one. Usually that fixes it.
If you can't find it anywhere, then it's hidden by code and no personalisation will help, you need a developer.
And if it all gets in a mess, clear the personalisation from User Settings and start fresh.
Is it a standard action or from an extension?
Glad to help - follow up if anything is unclear.
► If this solved it, marking it verified helps others too.
