Hi @digital_pk,
It seems you're getting some errors but, by defualt, errors aren't shown becasue security.
Maybe you can enable Magento's logs and see which kind of information you find into var/log/system.log and var/log/exception.log files.
Also, you can force those errors to be shown by adding this file:
/path/to/your/magento/instance/errors/local.xml
And into the file, this content:
<?xml version="1.0"?>
