Need help with WooCommerce website

Hello, Recently we've tried to update our WooCommerce and it has caused a number of problems with the website. It is functional but unsightly. The developer of our theme '"moved the theme folder from "wp-content/themes/bazar/bazar/" to "wp-content/themes/bazar/"' which fixed some problems of but made others considerably worse. I have a back-up from before this happened if it helps. It may be best to completely re-install WooCommerce + the customized theme but I want to minimize downtime. The faster this can be fixed the better. Please let me know if you would like to see the website. I need the following done- 1) WooCommerce updated to the latest version. When I try to do this we lose all of our product pages and some other issues occur as well. 2) If you hover over certain links in the header-menu the mega-menu appears almost off the page. This makes certain product categories almost unable to be accessed. 3) The FAQ page is severely broken and unsightly. The 'FAQ sidebar' does not display correctly at all. 4) In our product categories we have lost the ability to refine by color, product type and brand. This was a function of our theme which we have lost and seriously require. 5) The product pages now have the default WordPress blog sidebar even though they are set to the 'shop sidebar'. 6) The social icons in the header widget are now gone and display 'My Wishlist' and 'Compare'. This is not correct and looks terrible on all pages. 7) Gravity forms have been removed from over 1,800 products. When added again they show up in the product short description rather than above the price. I'm aware we'll likely have to add them all manually, though they need to be displaying correctly first..
