Automatically sign in even after clearing the cookies

I need to sign out and sign in again with another account. I cleared the cookies of https://themeforest.net/

However, whenever I refresh the page, it automatically logs in to the previous account.

Just to be clear, I can clear cookies of particular sites, not willing to clear cookies of all the sites.

What can I do?

have you tried with clear both browser cache and cookies? have you tried with another browser?

Have you clicked on sign out?

Cookies comes from envato.com and account.envato.com ( auto login )
Cleaning the cookies from ThemeForest won’t help you. You need to clean those as well

Yes. It’s frustrating that deleting cookies doesn’t work. It just automatically signs you in. Easiest way is to open a private/incognito browser.
