Hi, thanks for the question.
Can you give me some more details about how posts are being published on the front end. Are you using a custom form or are you using a plugin to provide this functionality.
If you are using a custom form, then you need to wrap the form code in the Limit Posts shortcode (EG [limit_posts type=”post” action=”publish”] your form code [/limit_posts]).
If you are using a plugin to allow you to perform front end publishing of posts then, if the plugin uses a shortcode, simply warp the shortcode in the limit posts shortcode as above. If it doesn’t use a shortcode then it is unlikely that you’ll be able to use Limit Posts as you want to.
Hope this helps,
Thanks.
