I've been working with CiviCRM for almost a year now. One problem we have is we frequently see the Internal Server Error 500 white screen of death. In particular, we cannot use the contact de-dupe tools. When we try to use them, the page runs for about a minute, then we get the error 500. Does anybody know how to diagnose what is actually failing when the error 500 happens? We are running CiviCRM 4.6.9 within Drupal 7 on Windows Server. Thanks for your help!

Generally, look for these logs:

  • CiviCRM's log (sites/*/files/civicrm/ConfigAndLog/)
  • HTTPD error log
  • PHP error log

Unfortunately, the locations of these differ by environment, and I don't know an answer for Windows Server.

Posted a similar (but broader) question: Where should one look for logs when debugging a new problem?
