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.
The Apache errorlog show this message:
Parent: child process exited with status 255 -- Restarting
Normally, this error occurs in 2 scenarios (as of now):
- After clicking the login button
- 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?
