Bug accepting new vendors

Good afternoon,

I’m using the vendor registration flow from WCFM plugin to automatize the registration of new vendors in my marketplace. In this way, the vendor can put all their data and wait for admin approval instead of us doing everything manually.

Although, in the moment of approving one vendor from the vendor approval dashboard, a black screen is shown with no data on it, just the black screen. When clicking anywhere, the screen is gone.

I’ve seen a similar post about it, but no further explanation or solution was given there. How can I proceed from this point?

I’m looking forward to your response.
