Forum rules
What to do if you have a technical problem with OCS:

1. Search the forum. You can do this from the Advanced Search Page or from our Google Custom Search, which will search the entire PKP site. If you are encountering an error, we especially recommend searching the forum for said error.

2. Check the FAQ to see if your question or error has already been resolved. Please note that this FAQ is OJS-centric, but most issues are applicable to both platforms.

3. Post a question, but please, only after trying the above two solutions. If it's a workflow or usability question you should probably post to the OCS Conference Support and Discussion subforum; if you have a development question, try the OCS Development subforum.

Premature end of script headers: php5.cgi - 500 Internal Ser

Postby lsirtosky » Sat Jan 26, 2008 3:48 pm

Hello,

I've just downloaded and installed OCS Ver 2.0 on my Dreamhost.com hosting plan.

When I try to go to certain pages (for example):
http://conference.jctonline.org/index.p ... index/user (User Home)
http://conference.jctonline.org/index.p ... Conference (Create Conference)

I get the following error in my error.log:

Premature end of script headers: php5.cgi

Here is a link to my site and to my PHPinfo file:

http://conference.jctonline.org

http://conference.jctonline.org/index.p ... in/phpInfo

At this point, all I have been able to do is set up my user profile, and click on the About page.

Any suggestions are greatly appreciated.

Lori

Hi lsirtosky,

I believe you can see more details of the error if you add the following line to your index.php, right after the <?php line:

ini_set('display_errors', E_ALL);

I can't login to your OCS site since I don't have your login info and I can't create a user account since there's no conference on your site to register for. So I wasn't able to see the phpinfo page or try going to User Home to see the error.

Regards
smiri

This line already exists in the index.php where you suggested to place it (line 2).

ini_set('display_errors', E_ALL);

I'll send you a private message for with login and password.

If you can help, I would totally appreciate it.

Hi,

you might want to have a look at this thread: http://pkp.sfu.ca/support/forum/viewtopic.php?f=8&t=2604&p=9173

I have a feeling you have a buggy version of zend optimizer.

smiri

Thanks for your reply regarding the buggy Zend Optimizer.

I believe I have disabled Zend Optimizer now via modifications to my php.ini file.

I added this line:
Code: Select all
zend_optimizer.optimization_level=0


When I look at my phpinfo(), now it says:

Code: Select all
Zend Optimizer
============================
Optimization Pass 1    disabled
Optimization Pass 2    disabled
Optimization Pass 3    disabled
Optimization Pass 4    disabled
Optimization Pass 9    disabled
Zend Loader    enabled
License Path    no value
Obfuscation level    3


Unfortunately, I am still getting the Internal Server Error.

Also, I can access my backend database via some of the pages. I was able to change my password, update my user profile, etc. I just haven't been able to do things related to the Creating or Viewing Conferences (kind of important part of this tool ;-) )

Hi lsirtosky,

What is PHP's memory_limit set to? Many sites use a default of 8M, and OCS often needs more, especially for administrative tasks like creating a conference. (Actual memory requirements depend heavily on the version of PHP you're using, but 16M seems to work well.)

My memory_limit is set to 90M.

This is a really frustrating bug.

As I have no real way to debug. Just getting the 500 internal server and the error.log messag is the subject of this thread.

Is there anything else I should be checking?

Here's my phpinfo for anyone who may be able to help:

Re: Premature end of script headers: php5.cgi - 500 Internal Ser

Hi lsirtosky,

Hmm, in that case, I'd still suspect Zend Optimizer. Even with all optimization passes disabled, you may still be encountering the debug_backtrace bug. Could you try temporarily removing all references to Zend Optimizer from your php.ini file? These lines should look something like:
Code: Select all
zend_extension_manager.optimizer=/usr/local/Zend/lib/Optimizer-3.2.2
zend_extension_manager.optimizer_ts=/usr/local/Zend/lib/Optimizer_TS-3.2.2
zend_optimizer.version=3.2.2
zend_extension=/usr/local/Zend/lib/ZendExtensionManager.so
zend_extension_ts=/usr/local/Zend/lib/ZendExtensionManager_TS.so
Just add a semicolon to the start of each line, restart your web server (or FastCGI, if you're using it), and try again.

Awesome, Alec (and gotta give the luv to Siavash too)!

Commenting out these lines fixed my issue.
Code: Select all
zend_extension="/usr/local/dh/apache/template/phpext/ZendExtensionManager.so"
zend_extension="/usr/local/dh/apache/template/phpext/zend_optimizer5/ZendOptimizer.so"

Hmmmm.... well this sucks that I can't use Zend Optimizer. But at least I can get on with my evaluation of this software. I'm hoping it will serve my client's needs.

If we do end up using OCS, is there any workaround for this debug_backtrace bug?

Thanks again.

When I realized it was working, I literally had the urge to reach through the computer and plant a big kiss on you! :-D

Hi lsirtosky,

Glad to hear it's working! You can get Zend Optimizer working again either by upgrading it to the most recent release (which I understand has been fixed) or by disabling the parts of OCS that use the Optimizer. To do the latter, you'll need to edit a few files:
  • classes/db/DAO.inc.php
  • classes/form/Form.inc.php
Look for any calls to debug_backtrace, e.g.
Code: Select all
                if ($callHooks === true && checkPhpVersion('4.3.0')) {
                        $trace = debug_backtrace();
                        // Call hooks based on the calling entity, assuming
                        // this method is only called by a subclass. Results
                        // in hook calls named e.g. "sessiondao::Constructor"
                        // Note that class names are always lower case.
                        if (HookRegistry::call(strtolower($trace[1]['class']) . '::Constructor', array(&$this, &$dataSource))) {
                                return;
                        }
                }
Prevent these blocks from running by adding a false condition to that first "if" statement:
Code: Select all
                if (false && $callHooks === true && checkPhpVersion('4.3.0')) {
You'll need to do this in a half-dozen places or so between the two files. Also make sure that the show_stacktrace option in config.inc.php is disabled.

This will disable some plugin-related features, but these shouldn't affect you unless you start writing your own plugins.
