Thanks for the reply Akshay,
May i get your email address so that i can mail you my site details.
along with this i am attaching screen shots..
1. when i try to open Product menu it takes too long time to load and once it loads it shows only 1 product list instead 20 products.

2. some of the products in the front end not at opening properly but this problem not happens with all products. few products only.

3. Site products and categories pages take too long time to load.
Once i deactivated the plugin everything works perfect.
