Magento doesn't save my catalog_product_set, what can I do?

I 've installed magento and it seems to work, but if I want to save a new Catalog_product_set with different attributes then I get Internal开发者_如何学编程 Error Message with Status Code 500

Does anyone have the same problem?

Thanks in advance cheers tabaluga

Your screenshot (and from the looks of it Magento's error page) clips the edge of the error off. Seeing the rest of the error message might be important. Regardless, it looks like Magento is trying to load a config file w/ simplexml, and cannot find that file.
