Notify Users blank screen

[JohnGrobler]

Good day,

We have two conferences hosted on a OCS site. On one of the two conferences, we receive a blank page when clicking on Notify Users (User Management > Director > Notify Users). The second conference renders the notifyUsers page correctly. I still receive a blank notifyUsers page after enabling show_stacktrace in config.inc.php. No errors are recorded in the Apache logfile. Deployment specifications:

OCS 2.1.1.2
Apache 2.2.3
PHP 5.2.0-8
MySQL 5.0.51a

Please let me know what I should try to resolve this issue.

Thank you,
John Grobler

Hi John,

Could you provide us with the output displayed when you turn debug to 'On' in your config.inc.php file? Also, you'll want to look in your PHP logfile for code errors, not just your Apache log.

Cheers,
Matt

I just experienced the same problem with OCS 2.3:

PHP Fatal error: Call to a member function _returnUserFromRowWithData() on a non-object in /usr/home/csbbcs/public_html/ocs/lib/pkp/classes/db/DAOResultFactory.inc.php on line 91, referer: http://2010.csbbcs.org/ocs/index.php/bb ... otifyUsers

The conference organizer wanted this email sent out last night. Help please.

Hi Trudy,

Could you also enable stack tracing to help us pin down what path the code is taking to get to this error?

Cheers,
Matt

[tshore]

I got nothing with the stack trace - just the blank screen still... I've also seen this in at least one other posting on this forum, but it was never addressed for some reason?

Hi Trudy,

This is a bug (it took me a while to realize because it only breaks when sending emails to registered users. Please apply this patch, and let us know if it fixes the problem.

Cheers,
Matt

[tshore]

Thanks Matt. That patch fixed it.
