on 2.80 install i followed tasks from https://www.nopcommerce.com/docs/80/upgrading-nopcommerce.aspx

Copied my *.txt files back after updated files.

Sql script ran fine.

Now I get this error:

403 - Forbidden: Access is denied.
You do not have permission to view this directory or page using the credentials that you supplied.

I confirmed and reset NETWORKSERVICE to all child folders.  Same error results.  2.80 was running perfect prior to update.

Did I miss something?
