Blank screen issue on localhost site when zend_extension for xdebug is loaded? (Win 7, Apache 2.2, cakePHP 1.2)

In a fairly large e-commerce site running on my localHost for testing, I get blank screens when the zend_extension for xdebug is loaded in the .../php/extensions/ directory and zend_extension = C:/UniServer/usr/local/php/ex开发者_如何学Ctensions/php_xdebug-2.1.0-5.3-vc6.dll is set in php.ini. Without it, the site works fine.

When I run a simple blog site developed under cakePHP 1.3 it works fine even with the zend_extension loaded.

My failing config is:

Windows 7; Apache 2.2.17; PHP 5.3.5; cakePHP version 1.2.1.8004; php_xdebug-2.1.0-5.3-vc6.dll.

Maybe the problem is caused by the fact that I am running a complicated site, or by the fact that I am using cakePHP 1.2.

I would appreciate any suggestions.

I had the same issue and it seems to be a xDebug version problem. To fix it I used the old xDebug (php_xdebug-2.1.2-5.3-vc9.dll) and it started to work fine. NOTE: I was trying to test a Magento 1.7.1 site with the last wamp version.

My local environment: WampServer 2.2E 64bit (Apache 2.2.22 – Mysql 5.5.24 – PHP 5.3.13 XDebug 2.1.2 XDC 1.5 PhpMyadmin 3.4.10.1 SQLBuddy 1.3.3 webGrind 1.0)

When I first installed, I assumed everything works fine. But when i performed my first debug, a blank loaded everytime I debugged. I know xdebug loaded since i was able to debug if I had a previous screen loaded and performing a submission. After using the wizard below and downloading the correct version, my xdebug worked.

Go here: http://xdebug.org/wizard.php

Apache should be keeping an error log. Check what it says when you get the blank screen. Usually a blank screen means there was a 500 error.

Since it's happening when you load a particular extension it's likely that PHP is unable to load that extension for some reason.

If you don't know where the error log is, look for the ErrorLog directive in your Apache configuration. That should give you the path to the file (might be relative to the Apache config path)
