Magento white screen or how XML can break your site?

By Sando on 02. Oct, 2012 in magento, small tips

I had an odd white screen on one of my websites. No exceptions, no messages, it was time to check the error log.

There I found the following error:

PHP Fatal error:  Call to a member function extend() on a non-object in httpdocs/lib/Varien/Simplexml/Config.php on line 600

That looked very scary like there was some mess withCore library of magento.

Actually it turned out it's not that bad just I hadMalformed XML fileUnder my"APP/etc/modules/"Directory.

Removed the file, you might need to use a bit of a trail and error here, and all worked as a charm.

Also make sure that you have there only XML files with". Xml"Extension.
