@JZandjans, happy Wednesday!
Thanks for reaching out to the HubSpot Community! Glad to help here.
I’d like to share this article on how to install the Wordpress plugin in HubSpot. Is this the integration you’re referring to? Or are you attempting to install in your Wordpress instance and you’re experiencing this loading behavior? If external to HubSpot, are you able to attempt the directions above from your Hubspot portal instead?
If that article does not help lead you in the right direction, can you provide a few screenshots of the behavior? (please make sure to blur out any sensitive information like emails or account numbers)
All the best,
Elyse
