Blank Admin Panel Still

I’m am still having the same problem:

I have the latest version of wordpress installed that does not require a SQL upgrade, my hosts do not have any plans to upgrade.

In FF after logging in a just get a blank page, in I.E. 6 it returns a page can not be found error. This appears to be very common?

I have tried a hack suggested on another thread which is taking the index.php file in the wp-admin and changing this line:

require_once('admin.php');

to

require_once('post.php');

This skips the dashboard, and allows you to edit and manage posts. The problem is if you try and edit anything – the browser asks if you want to save ‘post.php’ file – rather than executing the save command normally.

So it doesn’t really work as a hack.

I have tried all the workarounds recommended in the support section for this topic, resetting the passwords, firewalls etc., and of course re-installing WP.

Does anybody have any more ideas about this apparently common problem?

PHP Version 4.4.7 / mySQL 3.23.58
