blank page after login

[yijun]

Hi guys, i have just moved my magento site from one server to another live server. The homepage shows fine as well as the login page. But as soon as I logined, the page was all blank. And the url is http://www.domainname/index.php/admin/dashboard/index/key/(key value)/

My Magento version is 1.9.1.0

I tried many ways on the internet but still can't fix the problem. Can anyone suggest what I can do? Thanks a lot!!!

you have to check your magento error logs and php error log,

blank page means you have php error.

probably something is missing, broken file, or maybe even permissions

Thanks guys! Problem solved ! I found that the problem is on the hosting service environment and I added the bom extension then everything is fine now.
