Long loading leading to blank screen when try to access admin configuration page

[ethereal1m]

Dear all,

I just installed Drupal 7, everything works fine except after the installation I cannot access Administration Configuration page. I can access other pages without problem though.

 

The error was a long page loading, which leading to a blank screen. Could anybody give me a pointer how to troubleshoot this?

 

I have window7 64, PHP Version 5.2.17, Apache 2.2.21, mysql 5.5.

 

Best regards,

ethereal1m

Unfortunately many things can cause the "White screen of death", also called WSD or WSOD.

 

Best place for to try and start troubleshooting would be here.

I tried to add

error_reporting(E_ALL);
ini_set('display_errors', TRUE);
ini_set('display_startup_errors', TRUE);

 

on the beginning of index.php, but I still got nothing on the screen...

 

any other ideas?

I just fixed the problem. There are several issues:

First I got error of "anonymous user try to access" (I got this message by looking at drupal's log. I fixed this by running the following query to my mysql database:

UPDATE sessions SET uid = 1

 

then put the following line in the settings.php

register_shutdown_function('session_write_close');

 

The second problem was php max execution time was too low. For some reason it takes a long time to load /admin/config page. The fix is setting the following variable in php.ini

max_execution_time 120

 

The third problem was uncovered when I execute drupal status report, it is saying that drupal cannot access website, even though it was able to. So I fixed the error by adding the following line in settings.php

$conf['drupal_http_request_fails'] = FALSE;

 

That fixes the error, and magically fixes long execution on /admin/config page....
