Fix Magento issues

Our Magento store has a few issues that need to be fixed prior to launch: 1. Search for some terms results in a blank white page. We do not know why this only happens with some terms. Examples of words that trigger: "tea", "powder", "tea gift", and many more. Examples of search terms that bring results, "energy", "gift", "berry". All of these terms should bring results or at least a "no products found" page. Search was working 100% at one point, but we did a restore from backup, and after that search is not working properly. 2. Sometimes Bundle products will not add to cart. Clicking "add to cart" causes a grey loading screen but nothing ever is added. Here is example: [login to view URL] 3. On product details page, under section YOU MAY ALSO BE INTERESTED IN, it shows two products in scroller and squishes the images of the products. It also has overlap of <> scroll buttons onto images, and add to cart button overlaps text. This should be fixed and only one product should show in scroller at normal aspect ratio as with full size. This is for cel size responsive. 4. Top carousel on front page with 'Shop Now" buttons will auto scroll side to side, and manually scroll side to side, but if you touch in the area of the carousel to scroll page up or down in touch devices (tested were Iphone 6 and Ipad 2), it will not respond. Because this takes up most of screen in cel phone, user must be able to scroll down page easily. 5. Easy change of element background colors. Top Nav bar, Category bar, and bottom footers should be changed from current tan color to lighter color (#EFEAD9). Also, border around cart button in top Nav bar needs to be changed to match. 6. Selections in PAGES menu in footer should be bold and slightly 1pt larger text size. Site is: [login to view URL]
