Problem in loading products list page on admin side.

Hello,
recently I have shifted my domain. Everything is going well except product list page. When I click catalog/product it goes blank. When I renamed image folder content was getting loaded except images, but when i restored image folder again it goes blank. Anybody knows what would be the problem. I have checked my config file on admin side it is showing image folder path is proper.

previous query has been solved but now facing another issue I am not able to upload a product image from file manager. Pls help me out.
