i also encounter the same problem. i am on safari.
i installed HubSpot All-In-One Marketing – Forms, Popups, Live Chat plugin, and got directed to a page that said “HubSpot Plugin needs 3rd party cookies turned on for account security.”
unable to follow any steps as there was no way to access settings. i uploaded the zip file but it said the followings:
Unpacking the package…
Installing the plugin…
Destination folder already exists. /home/bangfore/public_html/a1vanilla.com/wp-content/plugins/leadin/
Plugin installation failed.
PLEASE HELP!!
