@PitaJ reply, top bar, and other functionality not working well in any browser.
Need some help, upgrade error.
just want to upgrade from 1.6.x to 1.7.x failed
Please guide me solve this error.
npm i commander --saveand try again.
As an addendum, it might help to
npm unl commanderbefore installing it. Try Baris' command first, and if no good, then run mine, then Baris' again.
@baris problem solved, many thanks!
