Prestashop Troubleshooter

We have a prestashop which is causing us problems. It is hosted with Bluehost. The version is 1.5.3.1. There are only 65 products with different attributes and price impacts. We tried to export the database and import it into a copy of the site hosted elsewhere. But the copy now has problems so we are trying to repair the original site. When we login into phpMyadmin there are multiples of the same tables which we feel may be causing some of the problems. So we need someone who is able to sort this out for us. The biggest problem is: 1. The categories showing on the website are not showing in the Back Office 2. The breadcrumbs show the sub-categories in completely the wrong hierarchy. 3. We cannot move some sub categories. We really need someone who knows prestashop very well and is excellent at phpMyadmin. We build a lot of prestashops so we would be likely to use this freelancer again in the future.
