Welcome to the PayPal Community! I'm sorry to hear you're running into some issues with your Business account. Have you tried clearing your cache, cookies, and browsing history yet? Normally, that does the trick for errors like this. If you're still running into issues after that, I'd recommend reaching out to our Customer Support teams by clicking "Contact" at the bottom of any PayPal page.
Apologies for the inconvenience,
