These two plugins do different things.
Guest Author Name Premium is not compatible with other plugins that use the guest-author post type. If you have Co-Authors Plus installed and want to be able to edit guest authors, you can download the plugin below to disable the Co-Authors Plus Guest Authors menu. If you do not do this, our guest authors menu will not be available on your dashboard for editing although Guest Authors that you enter while editing posts will be available in your posts. Guest archives will not be available.
Similarly, this plugin is not compatible with Monlogui. Again, you can enter guest authors while editing posts but guest archives will not be available.
Future versions may allow you to have both plugins installed by changing the post type name. Ideally you should not have more than one plugin that allows guest authors to be installed at the same time.
To disable just activate the plugin, allowing you to edit your guest author name authors and to enable guest archives. To re-enable, deactivate it to edit your guest author name authors. You can do this temporarily in order to edit your co-authors plus guest authors. Ideally you should not use more than one plugin that creates guest authors.
We will have an addon that allows you to add additional authors to a post in the very near future. If you would like to beta test this plugin, please contact us.
