403 Error when connecting the Klaviyo WP plugin to our Klaviyo account.
Dear community,
Unfortunately we passed the 60 days timeframe for support on our free account. We had some delaying challenges with our e-commerce store and now noticed that the Klaviyo Wordpress plugin wasn’t activated. So when trying to connect with our Klaviyo account again it gives us this 403 error.

What can I do this fix this?
Kind regards,
