White/ blank page is showing

Hello,

Just finish transfering the website. All domain  DNS is pointing to the VPS under CentOS.
Just now I am getting a white page when I put in my domain name or IP address with user.
What can be the issue?
In user account there is a domain name registered pointing to the user directory.

Try to put an index.html file with some text just to see if it shows.
If it does - there's a problem with your cms (assuming you're using one such as Wordpress or Joomla).

for white pages try to check apache logs, you have info about it on the wiki

I did put a simple index.html  and there is not difference.
Still showing me a white page

solution:
modified the index.php file where ENVIRONMENT set to development instead of production
