Broken Edit address link in sales order admin

Question

I am trying to fix the Edit Address links above Billing and Shipping addresses in Magento 1.6.1 Admin. They used to work, but stopped some time ago and I'm not sure why.

When you click either of the links, they try to go to the page to edit the chosen address as expected, but nothing loads - just a blank screen, and there is no source code behind it.

Nothing is logged in system or exception logs either!

I have found and followed this info: http://support.createhosting.co.nz/knowledgebase.php?action=displayarticle&id=55

But that didn't change anything on my development site (which is a replica of my live site to test this stuff on first).

How do I go about debugging and fixing this problem? Cheers!

In my experience, most often a blank screen indicates a PHP error. Oftentimes, this is indicative of a syntax error, but could also be a memory error (as in your case).

I would recommend looking at the PHP logs to see where the error is. To find them, check out this answer: https://stackoverflow.com/questions/5127838/where-does-php-store-the-error-log
