Blank page after clicking on Create issue

Postby Ajakss » Thu Jul 12, 2012 1:29 am

Dear,

As a editor I would like to create new issue but after clicking on Create issue (or Future issue) I get the blank page. I have changed the permissions but the problem remains the same. Furthermore, some of the management pages are unavailable (e.g. file browser). I do not know what should I do. The errors does not explain the solution:

ojs2 has produced an error Message: WARNING: Cannot modify header information - headers already sent by (output started at .../ojs/lib/pkp/classes/core/PKPApplication.inc.php:368) In file: .../ojs/lib/pkp/classes/template/PKPTemplateManager.inc.php At line: 295 Stacktrace: File: (unknown) line (unknown) Function: PKPApplication->errorHandler(2, "Cannot modify header information - headers already sent by (output started at .../ojs/lib/pkp/classes/core/PKPApplication.inc.php:368)", ".../ojs/lib/pkp/classes/template/PKPTemplateManager.inc.php", 295, Array(7)) File: .../ojs/lib/pkp/classes/template/PKPTemplateManager.inc.php line 295 Function: header("Content-Type: text/html; charset=utf-8") File: .../ojs/lib/pkp/classes/form/Form.inc.php line 209 Function: PKPTemplateManager->display("editor/issues/createIssue.tpl", Null, Null, True) File: .../ojs/lib/pkp/classes/form/Form.inc.php line 148 Function: Form->fetch(Null, Null, True) File: .../ojs/classes/issue/form/IssueForm.inc.php line 62 Function: Form->display() File: .../ojs/pages/editor/IssueManagementHandler.inc.php line 147 Function: IssueForm->display() File: (unknown) line (unknown) Function: IssueManagementHandler->createIssue(Array(0), Object(Request)) File: .../ojs/lib/pkp/classes/core/PKPRouter.inc.php line 370 Function: call_user_func(Array(2), Array(0), Object(Request)) File: .../ojs/lib/pkp/classes/core/PKPPageRouter.inc.php line 266 Function: PKPRouter->_authorizeInitializeAndCallRequest(Array(2), Object(Request), Array(0), False) File: .../ojs/lib/pkp/classes/core/Dispatcher.inc.php line 129 Function: PKPPageRouter->route(Object(Request)) File: .../ojs/lib/pkp/classes/core/PKPApplication.inc.php line 180 Function: Dispatcher->dispatch(Object(Request)) File: .../ojs/index.php line 65 Function: PKPApplication->execute()

Hi Adam,

Errors of the form "WARNING: Cannot modify header information - headers already sent" are happening because some earlier part of the code has already started sending output to the browser. Often this is an error message. Generally speaking, if you resolve that error message, this one will go away too.

Hi Alec,

thanks for your reply. I am quite newbie. Does my admin resolve this problem? What should I do in order to fix it? Many thanks in advance for your help.

Kind regards,

Re: Blank page after clicking on Create issue

Postby asmecher » Thu Jul 12, 2012 10:32 am

Hi Adam,

There are a number of cosmetic error messages there, i.e. they will not affect OJS's operation. You can fix them by patching https://github.com/pkp/ojs/commit/62424bde7950c54ff72c6598b8765ebcc3ffb009 and http://pkp.sfu.ca/bugzilla/show_bug.cgi?id=7229. The only reason they're causing you trouble is that your PHP is configured to display error messages to the browser. You should change your PHP configuration, i.e. using the display_errors directive, to direct error messages to a log file rather than to the viewer's browser. This will cause the "Cannot modify header information" error to disappear.

Hi Alec,

thank you very much for your assistance. I have fix them and these errors dissapeared. I think the php configuration has to do my admin.

Thank you again.

Kind regards,
