Instagram plugin error

Hello, I have the Inspiro theme updated with the latest version.
Since the last few months I am repeatedly having an error with the Instagram widget by WPZOOM, receiving a blank screen with the warning “Oops, an error occurred” every time I click on the Instagram widget in my website.

To resolve the issue I have to reconnect my Instagram account, but the problem happens again after a few days.

ps: I preview my site ( in different browsers and the problem happens with Chrome (my primarelly browser) but not with Firefox and Safari
