cimt67 Honestly, I do not know which folders have which permissions, because mostly this works just fine. And this is why I recommend doing a fresh install and move database, because then the installer takes care of everything.
If you need to find out access permission, just do a fresh install and look for yourself.
Also, maybe this helps: for the webpage to work, only index.php in root and assets folder need to be publicly accessible. The manager folder is needed only for manager tasks. All other folders should be ok if not publicly accessible.
