If you see this post it means that BlogEngine.NET is running and the hard part of creating your own blog is done. There is only a few things left to do.
To be able to log in, write posts and customize blog, you need to enable write permissions on the App_Data and Custom folders. If your blog is hosted at a hosting provider, you can either log into your account’s admin page or call the support.
If you wish to use a database to store your blog data, we still encourage you to enable this write access for an images you may wish to store for your blog posts. If you are interested in using Microsoft SQL Server, MySQL, SQL CE, or other databases, please see the BlogEngine docs to get started.
