I created a view block. I can see the view block on my page (node/30) no problem. Edited the view by adding filter criteria. I also changed "use Ajax to Yes". I can see the exposed filter in views edit page but I dont see the views at all on my actual page when I add the filter criteria. After I remove the filter criteria, I see the views again on my page. When i added the filter criteria, I also checked "exposed to user option.." I am not sure what I did wrong.
