I updated wordpress 3.1 on my blog http://www.mobidhoom.com and after updating everything gone messed up.
1) H1 and H2 not working, as code below in my Header.php ,
2) When someone send a comment in any post, it redirect to another post and comment also received in another post.
3) Permalinks and Pagenavi was not working so later I fixed it with help of few wp forum tricks.
So my traffic suddenly got down to 60% and going down and down.
Please some one help me.
