Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. Install Voaso CMS 0.7.1
2. Create a new page based Blog Article
3. Test that Blog Article is working (visit homepage for example)
4. Edit Blog Article structure and add a new field
5. Go back to homepage

What is the expected output? What do you see instead?
Expected output: the same homepage as in step 3
Real output: homepage gives exception
