Problem :

While doing the drupal 6 to 7 upgrade I am facing a not so helpful message

"The website encountered an unexpected error. Please try again later."

everytime I go to the certain pages. example) /admin/config

What is a best way to find out what is causing a fatal error so that I can fix it?

All I can think of right now is to start disabling the contributed modules until that the page works or looking through a logs.

Solution :

If your dlog/watchdog and php error log aren't working, try below:

Please go on /includes/error.inc comment line line 245

print theme('maintenance_page', array('content' => t('The website encountered an unexpected error. Please try again later.')));

and put below one

print theme('maintenance_page', array('content' => t('The website encountered an unexpected error. Please try again later.'.$fatal.' '.var_export($error,true))));

Very similar, you put the var_export($error,true)) at the end of error


By clearing your logs at /admin/reports/dblog then reloading a broken page I easily could identify a offending module when I rechecked a log.

Site is working fine for me now : )


To fix the issue please try below steps :

  1. Log into the database and run a delete from watchdog;
  1. Refresh a page
  1. Then execute a database query select variables from watchdog;
  1. Look out for a text near message
