Question

I’ve just installed Magento on my website, but I can’t access the backend. The frontend works fine, but in the backend once I successfully login, it takes me to a blank screen. I’ve read there’s an issue with cookies and I’ve tried a range of commenting out lines in varien.php, but didn’t work.

Answer 1

Go to /var/log/exception.log and check for any errors.

Alternatively in index.php just before the last line:

Mage::run($mageRunCode, $mageRunType);

put this

Mage::setIsDeveloperMode(true);
ini_set('display_errors', 1);

It should throw some sort of error now, and go from there.
