I'm running SS v2.2.1 on my site. I've also set up a news section using the ActiclePage and ArticleHolder page types. It's worked great for me up until the point that I installed the blog module. As soon as I had the two running on my site simultaneously, the news section stopped allowing me to publish articles. I continually get an error upon publishing that says: "Error Saving Content." Any ideas as to what might be causing this and how to fix it so that these two can coexist on the site?
