I’m still chasing down this 404 error. As a test I did a new install of WP and reinstalled the theme without dummy data. I set the Permalinks to post-name then created a portfolio. After saving I attempt to view the portfolio and get a 404 not found error. If I set the Permalinks to ‘Default’, the portfolio can be viewed.
What’s up with this?! I cannot use this theme with Default Permalinks. That totally throws SEO out the window. You guys need to get this fixed!
