Question: I've moved my blogs from SP2010 to SP2013, and the original **Posts** Web Part doesn't render correctly, it shows the error

I'm replacing this web part with the SP2013 version, but this is showing me my posts in a tabulated form, like this:

When I try the `Blog Tools` -> `Change post layout` nothing happens. I cannot get the layout to be `Inline`, as I'd like it.

Any ideas what's going wrong?

Answer: 
Make sure first that the selected view is "Summary View".
The inline, Basic and Boxed styles work only with "Summary View"
The easiest solution is to reactivate `BlogHomePage` feature `{E4639BB7-6E95-4E2F-B562-03B832DD4793}`. It will re-populate the homepage with new `default.aspx` with all webparts.
