I’m also using the kleo theme and can’t write on the front end either as admin, author or subscriber. I can only write from the backend. I’ve selected ‘Creative Writing’ and believe all the taxonomies are set up right.
You should also check to ensure the plugin is working with the ‘WP Content Copy Protection & No Right Click’ plugin and it’s important to protect the content for writers. Perhaps you can suggest another content protection plugin that has been tested. Thanks for this plugin.
