I am new to magento. I hired a developer to set up a fresh install in a directory of a live site, in addition to ssl. Everything worked fine. After not looking at the site for almost 3 months (project was on hold) I tried logging into admin and get a 404 error. I've searched online to try and find solutions - manually cleared the cache, but still not able to get on. I went into phpmyadmin and located the database - it contains no tables. I don't think that's normal. Any ideas what I should do? Unfortunately I don't have a backup of the database.
