What happens when you go to:

I can see your admin login screen. If the login doesn’t recognize your password it could be that you had a different password at the time you took the database backup. Can you remember your old password? If not, and you go to:

are you sent an email? Again, if your email address has changed you should use the email at the time you took the database backup.
BTW, when I posted last time I should have given a fuller answer about cache. You were running a plugin called WP Super Cache. This plugin keeps a copy of pages. When someone wants a page at a later time, they get the copy that was made earlier. This is much quicker and normally a good thing.
But when you are going through a period when you are developing and changing things, that old copy of the page is linking to things that aren’t there any more, and your page gets screwed up.
When you are making changes (assuming you can get back in!) you must turn off the cache in the plugin settings until you have finished making changes. Also look for and click the “Delete Cache” button. This will delete any old pages that are no longer valid.
Changing themes – don’t be afraid to do this. In WordPress, themes and content are separate. So you can change themes several times, and if necessary go back to the first theme. This is a useful way of trying to identify whether an issue is due to a theme incompatibility. Generally if there is a problem you should try the default theme TwentyFourteen. If that fixes the problem you know the cause is an issue with your preferred theme.
