How can I debug a PHP Web Application's (Magento specifically) Installation Flow?

I can't get passed the Magento Installer's Terms of Service. After clicking the Accept check box and clicking Submit, the page (seemingly?) refreshes itself.

I’ve changed perms to 0777 with this开发者_JAVA技巧 script

#!/bin/sh
find . -type f -exec chmod 644 {} \;
find . -type d -exec chmod 777 {} \;
chmod o+w var/.htaccess
chmod 550 mage

and also tried disabling the script with no avail.

I am installing from http://www.mydomain.org/2/index.php/install/wizard/beginPost/ with no avail, I thought I would mention the path just in case.

Is this a common problem with the system? If not, how can I debug what's going on?

UNSOLVED (this only took care of one issue, there is evidently more issues afoot)

EDIT There seems to be an issue with possibly getPost in not properly passing the argument correctly?

Your post is thin on the details someone would need to debug this for you. Two tips.

1. You shouldn't be starting the install on install/wizard/beginPost. Instead, just load the root level domain name with no path, and let Magento direct you where it needs you to go (you may already be doing this)

2. The installer, like the rest of Magento, is a Module, which you may debug. Its controller is located at app/code/core/Mage/Install/controllers/WizardController.php

Adding temporary debugging code into the beginAction and beginPostAction to figure out what's going on is your best bet

You can install via CLI to get around the web based installer issues (usually), I've encountered some anomalies before when installing: http://www.magentocommerce.com/wiki/groups/227/command_line_installation_wizard

It may help also shed some light on why the web based installer isn't working if any errors are thrown, both during installation and after.
