No Magic Button?

I’d setup a redirection and then didn’t need it, as it turned out. I deleted it but the redirect was still in effect. I deleted the plugin but the database tables remained. I delete the database tables. Now, only the home page comes up. I’ve tried deleting the htaccess file – no help.

I tried reinstalling the plugin but getting the error ‘Redirection not installed properly’ – I don’t see a Magic Fix button.

Help!
