I recently updateted to civicrm 4.6.4 on drupal 7.38. While entering contact data, I found when a contact has no address by its own, but a referral to another contact's address, edit using the edit button gives a fatal error.

Fatal error: Cannot pass parameter 1 by reference in /var/www/html/drupal/sites/all/modules/civicrm/CRM/Contact/Form/Edit/Address.php on line 363

No further info available like stacktrace,...

How to reproduce: - create new contact - save contact - edit contact (this is working!) - search for the new created contact. A list is presented with the searched contacts. - choose edit on the end of the contact line.

inline editing while viewing a contact is still working.

Any ideas?


  • I manage to create the same in Demo but I am not getting any error message - please do the same example against demo site (d46.demo.civicrm.org) and if you are still getting the error message please let me know how to reproduce - thanks Jul 10, 2015 at 11:51
  • Hi, also for me it is not reproducable on the demo-site. As I'm not having much of an error, it's hard to debug. Jul 10, 2015 at 12:22
  • did you manage to do John step's which he has given below Jul 10, 2015 at 13:28

John guided me to the solution: civicrm is located in Belgium where adresses should be "street number bus" and second line "postalcode city". I used the civicrm (alpha) extension "org.civicoop.streetformatnl" v1.0 to edit civicrm views. Unfortunately it is no longer compatible. If disabled, everything works fine.

Kind regards, Johan.


Could you check that you updated correctly, and there there are no PHP files overriding the default CRM/Contact/Form/Edit/Address.php file?

There is a description of what this error means here: http://php.net/manual/en/language.references.pass.php

(Googling for the error reveals a few example solutions.)

I've checked line 363 in the 4.6.4 codebase, but I can't see anything that would break it there: https://github.com/civicrm/civicrm-core/blob/4.6.4/CRM/Contact/Form/Edit/Address.php#L363

Can you confirm what line 363 is in your CRM/Contact/Form/Edit/Address.php file?

    Also check for incompatible extensions, tpl and php overrides, custom hooks, etc.

  • - By my knowlegde, no php overriden by me (I didn't program php myself). - Address.php is exactly what it should be. Line 363 contains "))," like your link set so. Jul 12, 2015 at 18:18
