I am working in a intranet site with Drupal 7.12. Once clicked the login button, after providing the user name and password, I am getting the following error:

Internet Explorer cannot display the webpage.

Sometimes I get the following JavaScript error along with the above error.

javascript error : Access is denied Code:0 URL:

The Apache errorlog show this message:

Parent: child process exited with status 255 -- Restarting

Normally, this error occurs in 2 scenarios (as of now):

  1. After clicking the login button
  2. After changing the password of another user, and clicking on the save button

During the above error, the header part is still displaying.

Is it a Drupal related problem, or Apache/PHP/MySQL related? Could you please suggest me that how to solve this?

Is this a fresh Drupal install? How long was it working and with what modules? – Johnathan Elmore May 17 '12 at 14:04
It looks like Apache is crashing. What version of Apache, PHP, and MySQL are you running? By "drupal header" do you mean the top part of the web page or the HTTP header? If the former, what block is supposed to display immediately after the part of the page that displays? – choster May 17 '12 at 14:38
Is it doing this in other browsers, or just IE? – Chapabu Jun 17 '12 at 10:52
This question appears to be off-topic because it is about a bug in Organic Groups, as mentioned by OP in this comment. Bugs should be reported in appropriate issue queue, not here. I'll retract my close vote if OP will provide an answer that will describe how he found it was a bug. – Mołot Feb 24 '14 at 8:20

Try commenting out the whole bottom part of main htaccess:

  <IfModule mod_headers.c>
    # Serve gzip compressed CSS files if they exist and the client accepts gzip.

just to see if that is not the cause.

Hi Artur, I tried your suggestion. Commented the .htaccess entries as you suggested. Its not working. I am getting the same 404 error. – Sundararaj Govindasamy May 18 '12 at 3:15
Hi Johnathan Elmore -> This is an intranet site working for last one month. Main modules are advanced forum,flexible blogs,organic groups,ckeditor etc. – Sundararaj Govindasamy May 18 '12 at 3:25
Hi choster, I am using Apache 2.2.22 PHP 5.3.10 and MySQL 5.1.62 and Drupal 7.12. I mean the top part of the web page as drupal header. After the above senarios, the page is supposed to display is the Home page (localhost/Drupal1/node). Please suggest me to solve this.Is this Apache problem or Drupal problem? – Sundararaj Govindasamy May 18 '12 at 3:25
Friends, I found the rootcause. Drupal Organic groups 7.x-1.14' sub module og-field-access is causing the problem. When i disabled that module, now the 404 error is solved. – Sundararaj Govindasamy May 18 '12 at 13:41
Please write this as an answer and file an issue with that module's queue so the maintainer has a chance to fix it for others. – David Meister Jan 19 '13 at 13:16
