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.

Found the issue. Not sure how it happened but my adminhtml directories from app/design/ and skin/ had been mysteriously deleted. I brought the dirs from another Magento install and everything is working fine now.
Thanks for the help!
