This plugin adds an option to override this behaviour, so that the theme will behave either as a single author blog (even where there are multiple authors) or as a multi-author blog (even where there is only one author).
- Activate the plugin through the ‘Plugins’ menu in WordPress
Or install through the WordPress.org plugin directory and activate.
After activating go to Options > Multi-Author Override
You can set the option here to force the theme to display elements as if it were a single/multi author blog, regardless of whether there are posts by multiple authors or not.
The options are:
* Always display as if single author
* Always display as if multi author
