I am getting the WSOD now since editing settings.php; php.ini and .htaccess trying to update my site and I need to see error logs to find out what is happening.

Also how do you clear cache in command line?

First of all:

  • The logs for apache are set in the httpd.conf file.
  • And the logs for PHP (if any) are set in the php.ini file.

For the case of PHP, you have to look at the php.ini file, and look for log_errors and error_log variables, that must have these values:

log_errors = On
error_log = /tmp/php_error.log

the last value (/tmp/php_error.log) is just an example. It must be a path to a secure location where you want to store the logs.

Make sure that:

  • these two lines are not commented, i.e.: they cannot have any ; before them.
  • after the edit is done, restart apache to load these values.
  • error_reporting(E_ALL); ini_set('display_errors', '1'); – freja Dec 3 '12 at 13:46
  • read the above works as well but did not notice any errors in php.ini. I think I need to dump the database which I am also unsure of how to do without making a mess. – freja Dec 3 '12 at 13:48

In my experience, PHP's error messages will appear in Apache's error log by default. Try checking there (it's /var/log/apache2/error.log on Debian) for messages mentioning PHP.

    I read that too and found a command to reveal error_log but when I looked for it to edit couldn't find. – freja Dec 3 '12 at 13:50
  • This is great thanks, I found it in /var/log/httpd/error_log and it seems some files are missing like robot.txt so thanks again. – freja Dec 4 '12 at 1:51
