Cannot select personal plan

Question:
I’m attempting to upgrade my Wix plan to a personal one so I can connect my custom domain and access other features. However, when I click on the upgrade option, it only presents me with choices between the business plans, which are a bit pricier than the personal ones. Even when I select the personal plan, the page appears blank.

Wix Studio
