i recently upgraded apache and php on my server.
PHP 5.2.3
Apache 2.2.2 (Win32)

Ive had the debugger module running on several other machines without any problems, and i have the file in the correct location, but it doesnt work.
Here is the part of my ini file that contains the debugger stuff.. if anyone could give me any clues.

[Zend]

[Xdebug]

xdebug.auto_trace=On
xdebug.profiler_enable=On

[Debugger]
debugger.enabled=On
debugger.profiler_enabled=On
debugger.ports=7869, 10000/16
debugger.JIT_enabled=On
[Zend]



zend_extension_ts="c:\Zend\Core\lib\phpext\php_dbg.dll-5.2.x"
zend_optimizer.enable_loader = 0
zend_optimizer.optimization_level = 15

ZC uses custom build of php modules and have made their php incompatible with all other modules.
If you have no particular reasons to run ZC instead of free distributions based on Apache (like NuSphere TechPlatform or XAMPP), I'd recommend you to switch.
