Hello, my members and I am also currently experiencing this error. I am using the default Invision theme on version 5. I am up-to-date. Any idea how to fix this so when a member logs in, they are taken to the correct page and not this error page?

Example: Member is on my home page -> clicks a topic that is for members only -> taken to a page that asks them to sign in or sign up -> member signs in successfully, but is met with that error message

Do you have an example topic I can visit to test this? Also, have you tested it without the ads? Asking as thats the first thing I notice when clicking a new page
