CiviCRM Community Forums (archive)

Can someone explain to me the steps I need to take to enable debug and backtrace? The documentation on this is a bit spotty.

We're using Drupal 7.2, CiviCRM 4.0.0. (I downgraded from 4.0.1 because of some problems, but they've persisted.) Things were working fine on a Drupal 6 / CiviCRM 3 sandbox. Problems began when I imported the CiviCRM database to a fresh Drupal 7 / CiviCRM 4 install (different domain name, different server, brand new Drupal database) and imported the CiviCRM 3 data. I ran into some issues but was able to eventually run the upgrade script for CiviCRM.

My site has a lot of custom data. Under certain circumstances that seem to involve how many custom datasets are enabled, I get this error when I try to edit a contact:

Sorry. A non-recoverable error has occurred.
QuickForm Error: element already exists
> Error Details [this should expand, but doesn't]

A couple times, instead of Error Details it has displayed "unable to determine value for ct".

I'm also getting this error message at the top of most pages: Undefined variable: return in _civicrm_api3_dao_to_array() (line 351 of [path]/sites/all/modules/civicrm/api/v3/utils.php).

It's been suggested to me that I try to run debug and backtrace, but I'm a bit unclear how to get started. Thanks in advance!

m.e.

Thanks.  The output is

...suggesting a problem on the Drupal side, or perhaps how CiviCRM communicates with it?   This occurred when I clicked "Edit" for a contact.
