From there I cannot log in as an admin, it is just stuck on this page.
Once the new files were uploaded and I went to the install link, I was taken to a regular install link, not the upgrade link.
As instructed by the install process I uploaded a new config.php file, but xenforo wants to rewrite everyting, start from scratch, and I can't have that.
Edit - I will add that the forum was closed, maybe this has something to do with the upgrade not working correctly?
Edit 2 - I did the upgrade via a mac and Coda. Did I overwrite everything, maybe files were not merged? Ugh.
