Magento - Unable to add products + edit contact page

Adding Products I am unable to add new products, I think the reason for this is the color attribute that I added. When I select a color attribute it says it saves, but it does not. And the product is not listed. Before this problem started I tried to change the color attribute from a single select drop down to a multi-select. I think this is the cause of the problem. The most recent product I added is the Grecian Urn Tote, this is when I noticed the problem. All other products are working fine, but new products do not show up. I need this fixed so that I can add products as normal. Contact Page: - Remove the left side bar with "comparable products" and add some images of bags. Similar to on the FAQ page, but use different images. - Currently the emails say they are from "owner" and "" change this to pull the Name and Email from the form. So it looks like it is coming from the customer and the reply is sent to the customer. Please let me know if there are any questions about the two above tasks.
