Logging into Salesforce generates this error:

This page has an error. You might just need to refresh it. First, would you give us some details? (We're reporting this as error ID: -78170657)

This happens on initial page load. Any ideas how to resolve?

  • Have you tried looking at the browser console to see if you have more information about an error from a component in the page?
