Delete default 'blog' breaks the blog app
I am just setting up a new site with Runway and the new blog app. I wanted to create two blogs. 1.News and 2. Stories. So I installed and setup the blog app etc. I went into the app in the back-end and created a new blog called news. I then proceeded to delete the default 'blog' blog and after doing this I now get a 500 error when trying to access blog in the back-end menu.
I looked in the logs and I get this error;
