This site worked great at DNN 6.1.5
Upgraded to DNN 6.2 and can't access it as localhost (works OK as website)

I've done 10 or 20 upgrades and never had to do this ... but did "unblock" and reran upgrade 6.2 ... overwriting all files

I still get the security warning on local host but not as a website. Note I'm trying both using a browser on the server. I can also access the website remotely. They have different IPs.

It occured to me that I should check the 6.1.5 DNN on local host ... yikes, they're getting a 500 error. As my host installs security patches, perhaps that has messed something up? Looking at getting those up first as local host. All sites are OK as websites.
