Access Denied Backtrace Documention is Badly Outdated and Could Use Updating

Same issue.

New Drupal 7 setup, with ADB enable and configured but no backtrace in the access denied logs

Got the same issue -

Code looks for $log_entry['type'] = "access denied" but Drupal 7 generates

$log_entry['type'] => page not found

Look in function adb_watchdog($log_entry) to change

The documentation is outdated. You cannot see this from '/admin/reports/dblog'. It's now at: '/admin/reports/access-denied/backtrace'.

Still no dat ain the backtrace.not on
/admin/reports/access-denied/backtrace

or in the reports

The link to the backtrace is actually there, just has no text between the a tags to let the user click on it. If you inspect the table within your browser, you can get to the link.

EDIT: I don't have much time to discuss this, but the problem lies within _ddebug_backtrace not returning anything, as

variable_get('error_level', 1) >= 1

seems to always be false. A quick solution for me was to return $backtrace just before the function closes.

I also believe that

    $user_role_permissions = (isset($role_permissions[$log_entry['uid']])?$role_permissions[$log_entry['uid']]:array());

should be

    $user_role_permissions = (isset($role_permissions)?$role_permissions:array());

although I could be wrong. Just my quick thoughts.

Thanks bendiy & drupalmoff!
That worked. Knowing where the info should be was helpful of course.
I don't have "error_level" in my database, at least not on dev, so it's no wonder that conditional returned false. I just removed the if altogether.

Did you commit it. I still see no access denied backtrace stuff.

@truyenle you need to enable "Errors and warnings" at /admin/config/development/logging
then visit /admin/reports/access-denied/backtrace

It is indeed /admin/reports/access-denied/backtrace you have to visit.
Should be added to project's documentation.
