This happens where there is an error on the server side. The first step to troubleshooting this is to look at your error log to see the exact error that is occurring. Most hosting providers give you access to the log within your hosting control panel.

You could also temporarily add the following code to the top of Drupal's index.php. This will usually cause the error to be displayed rather than just a blank white screen.

Here is a page detailing the troubleshooting of the "white screen of death" as it's known.

Well, I spoke to tech support and they asked me what version of php I was using locally, I went to drupal status report and it says I am using 5.4.10. So they set the server to php4 for my website and I got this error:

Parse error: syntax error, unexpected T_CLASS in /home2/winter/public_html/bpfdev/includes/bootstrap.inc on line 306


When they set php to 5, I got the white screen again. So, I am pretty confuse what should I do from now.

Could you please help me?

Thanks

The white screen means there is an error occurring. As I initially stated, you need to find out what the error is by viewing the logs or getting the error to display. The issue may have nothing to do with the php version. You need to know what the error is before you take any steps to solve the issue.

Oops, it looks like I forgot to include the code snippet with my original response.. If you can't view your error logs, add this to the very top of your index.php file. This will cause the error to display in your browser. Errors are hidden by default. Be sure to remove this from the file when you are done troubleshooting.

<?php
error_reporting(E_ALL);
ini_set('display_errors', TRUE);
ini_set('display_startup_errors', TRUE);
?>

Hello,

Well, I ended up contacting tech support and he told me he had to move krumo out of the way. For some reason it was causing conflicts. I don´t know why.

 Thank you expert, you knew it was from the server side, that is why I contacted tech support.

Thanks!

If you had krumo installed, I'm guessing you were using the devel module. Be sure that you properly disable the module so that it doesn't cause more problems because the krumo files have gone missing. Also, updating the module will reinstall krumo and break your site again.

Where you able to find out the actual error? Knowing what the actual problem is will help keep you from having it again in the future.
