I've been dealing with a problem all morning where my website is working just fine but I can't access the admin panel. It's not that I can't log in, I can't even load the admin login screen. It was working perfectly yesterday.
The resulting page when accessing the admin is a completely blank page with no HTML, just a basic response header.
To make matters worse, I'm not being able to make the Magento log work, not even through
Mage::log("something to log")
when it's placed in Mage_Core_Controller_Varien_Front->dispatch.
PHP(apache) not throwing any errors either. Log files do work for apache.
I'm really out of ideas for this one. Any thoughts would be greatly appreciated.
