Title: suggestions to fix 3 possible issues 

1. Change the layout for all xml feeds from nil to null - this removes "Unable to find nil layout" error on generation
2. Add categories.html to article
3. Date was not shown - apparently post_date_formated was not set. Using date_time_html should fix the issue
