Thanks much Andrea, I'm so very new to SEO and all the errors freaking me out!
Yes the migration changed the URL structure. I thought I went through them very carefully to make sure each URL matched (not sure why not all of the URL successfully submitted with matched URLs).
I also upload all the previous redirects via Yahoo onto the new platform.
I updated the new sitemap to the search engines (Google, Yahoo)
For example, the below links showing as errors and can't figure as too why. I updated the sitemap:
http://www.shopchameleon.com/a-black-mesh-bow-belt/index.html
http://www.shopchameleon.com/a-black-mesh-bow-belt/privacypolicy.html
http://www.shopchameleon.com/ballerina-cool-earring/testimonials.html
But also strange that when migrated and w/ all these errors the website is getting double amount of traffic??
