Where can I change the default category?

The plugin uses the defined default category to automatically assign it to every new post. There are various ways to use the default category, which are described here.

About the WordPress settings

1. Go to Settings > Write.
2. Here you can specify this in the „Default post category“ field.
3. Save, done.

About the category list

The plugin provides an option to change the default category here too. To do this, call up the list of categories under Posts > Categories. You will then see a „Set as default“ link next to each category. Click on this to make the category the default category.
