Basically quite a while back a friend of my installed a blog theme (maybe hacked) awhile back here at http://www.DasCheap.com/costumes/home.html
You can see the link for the WP blog at the bottom footer where it says blog in the image (so at least you know it's linked throughout the site, and basically I think that the person who was in charge installed a hacked theme.
My question is that we had some good traffic to it, and all of a sudden it seems to get very little (almost none). Content is pretty regular and clean. Can someone suggest any way to find malicious code (if any) in the theme just by looking at source or perhaps the best SEO plugin that is result driven?
I feel like all of our work is pretty toasted.
Thanks in advance!
