Anyone else having these issues with version 1.6.0?
Here is some more detail:
When debug mode in wordpress is false (off), you can’t add a new post (500 error) with the latest version 1.6.0.
When debug mode in wordpress in true (on), you can add a post, but sometimes you can’t then display the post and get a 500 error.
This is the error you get when you click the Add New Post when debug is true (on)

The temporary solution is to use version 1.5.1
