Can't log in as admin Someone let us know about an error on our site. I logged in (as an admin). I was able to move the site to maintenance mode and then went through the steps to clear the cache on the site. Once I did that, I am no longer able to log in or even get to the log in page.  I went to our site: safefields.org/user and I get this error: safefields.org is currently unable to handle this request. HTTP ERROR 500  How can I fix any of this if I can't even log in?
When you type in safefields.org/user your site immediately redirects to the login page safefields.org/user/login which I believe indicates that your Drupal site is running but gives you a WSOD (white screen of death).
Usually that is because of a memory_limit constraint.
Things to investigate:

Try to use Drush to set the maintenance mode back to 0: drush vset maintenance_mode 0 this should get your site visible again
Check your settings.php and see if you have a memory_limit set there, increase to 512M or higher clear cache (either via Drush or empty cache tables directly in the database)
Check your php.ini file either in the root of your site's folder or in your public_html folder and increase it in size.
Google &quot;Drupal 7 WSOD&quot; as they say: add error reporting to your settings.php file to see what the errors are so you can search more effectively for what's causing your problem. https://www.drupal.org/node/158043

error_reporting(-1);
$conf['error_level'] = 2;
