Hi,

I upgraded my site to 4.8.3 without any errors during installation. However, when I try to access some of the admin or host pages I get the errors below. Also, there does not seem to be any error logging happening. I have ensured that all the new dll's were copied over.

 Error: Host Settings is currently unavailable.

Thanks,

My previous version was 4.7.

To upgrade, I created a backup of the entire site. Then copied over the configuration settings (db con string, machine key, etc) to the new installation. Then copied over all the new files on the site. The site upgraded itself (no errors).

None of the other pages on the site have this issue. Only a few select pages under admin and host have this issue.

Thank you for your help.
