To deactivate an affiliate, you must locate their account on the "Affiliates" page. First, click on the "Affiliates" option in the navigation to the left.

Once there, find the affiliate whom you would like to deactivate and click on their email address. You can use the search field to filter results and the column headers like "Email" and "Name" to sort your affiliates.

Once you've found the right affiliate and navigated to their individual page, you will see a display of their information. On the top right, you should see a green button that says "Active." Click that button to reveal a dropdown menu, and select "Deactivate" to deactivate that affiliate.

Please note that your affiliates are notified when changes to their accounts are made.
