So I'm struggling to set up CustomPress on my website. Frustrating to say the least. I've created a new content type and taxonomy and went in and added a couple of entries. Then I went back and tweaked the settings. Now I can't edit the existing posts (I only see "View" not "Edit") and I "don't have permission" to create new entries. I've gone back and redone everything I changed, but nothing let's me back end. What did I do wrong? Can I fix it? If not, can I delete everything and start over?
