Bladesman, maybe this is related to your web host ?
If you’re trying to run a business, think that time equals money. If you spend DAYS on it, you’re losing considerable money.
I’d recommend that you try with another web host, and see how it goes.
There are quality (I mean it) web hosts that are inexpensive nonetheless, like hostgator’s baby croc plan (I was with them for a year for a few blogs). You create your hosting account in there, reinstall wordpress from scratch and see if it works, and then you replace the database with a backup of the database (see if this works), eventually restoring also the wp-content/ files that were added by you (and see if it works).
If you redirect your domain name to the new host (changing nameservers @ the registrar) it takes 24 hours only and sometimes only a pair of hours (you can check dns propagation on whatsmydns.net and subtly change somemething within your blog theme, like text in the footer, to tell if it’s the new server).
If it works : blame your web host, and start working on your biz ??
If it doesn’t work, at least you can rule out your web host.
