Export of contacts fails Export.php:600 (after upgrade,doesn't´matter if 1 or 8000).

Hi all,

unfortunately, after the upgrade to 4.5.6 we have some troubles with exporting contacts.
It doesn´t matter if we use 1 contact or 8000, we are linked to a white screen with following error message:

Any hints how to solve this problem?
The civihosting provider support didn´t feel responsible for this issue.

Best wishes, Michael

Hi Michael,

The issue is that when PHP programs like CiviCRM generate a CSV file (or any file that's intended to be downloaded), the generated file must contain nothing but the CSV.  That is, you can't load part of a page, then say, "OK, make this a CSV to download".  Unfortunately, CiviCRM is generating a warning before it generates the CSV, then it's saying, "Hey, because I already sent this warning to the screen, I can't generate a CSV".  That's the "cannot modify header information - headers already sent" warnings you're seeing - it's because CiviCRM reported that first warning to you.

So there's three solutions here:  Fix the warning, work around the warning, or suppress the warning.

* The warning seems to be introduced by work done here https://issues.civicrm.org/jira/browse/CRM-15301.  A coder could probably fix this without much work.
* If my quick reading of the code is correct, the problem comes up only when your contacts aren't sorted.  Try clicking on a header of your search results to sort them before you export, let us know if that fixes the problem?
* Finally, you can suppress warnings: http://php.net/manual/en/function.error-reporting.php.  I suspect this is why we don't see the same problem on the demo server.

Thanks JonGold,
terrific.

Since nr. 2 doesn´t work, I will try nr. 3 for a test:

error_reporting(0);

In which php file would I write this command?

Best wishes and thanks, Michael

Best to set that in php.ini like this:
Code: [Select]
ini_set("error_reporting", 0);
Otherwise...I'm not 100% sure!  wp-config.php perhaps?
