Hey Simon,
first of all, thank you for the purchase!
By design Ikebana has two segregated post types, of which the classic posts are displayed on the blog page, and the projects are displayed on the page with “Portfolio” template. They both, however, use the same set of php files to display the content, which is why in principle the’re quite interchangeable, given some php customizations. Could you please tell me what is the purpose of displaying the posts on portfolio grid, and do you wish to display only posts (for example, after importing content from another blog) or both posts and projects on portfolio pages? I will prepare a custom template file for you once I have more background information.
Sincerely,
Andrii / Satori Studio
