Comments on: Magento: Error – SimpleXMLElement::addAttribute() Attribute already exists http://www.sharpdotinc.com/mdost/2009/03/10/magento-error-simplexmlelementaddattribute-attribute-already-exists/ Just another Sharpdot weblog Tue, 27 Jul 2010 14:58:23 +0000 http://wordpress.org/?v=2.9.2 hourly 1 By: Brendan Falkowski http://www.sharpdotinc.com/mdost/2009/03/10/magento-error-simplexmlelementaddattribute-attribute-already-exists/comment-page-1/#comment-260 Brendan Falkowski Tue, 08 Dec 2009 15:58:24 +0000 http://www.sharpdotinc.com/mdost/?p=79#comment-260 This helped me out. Inside catalogsearch.xml I was removing breadcrumbs from the default layout (which is global, bad idea). Inside checkout.xml I was removing it again from the "checkout_cart_index" layout, which caused the error. Once I changed catalogsearch.xml to use the appropriate sub-layout instead of "default" everything was fine. Avoid placing things in default if you can. Literally every page loads them, even if the page code is from another layout entirely. This helped me out.

My problem was that I had added the newsletter block to a page using a custom layout file, but the newsletter block was already being included by the newsletter.xml layout file. This meant that I was trying to add it the the same area twice, and that is why this error message got displayed. I would retrace any changes you made to the files in the layout folder. If you are using SVN or CVS try rolling back till you get to a point where this error no longer shows up. To sum things up it is very hard to impossible to say why you are getting this error thrown. You just need to identify when it started and look at what you changed. Its hard to say what exactly is causing the problem.
