I am begging you to do a screenshot tutorial of how to change the type of your post with the web inspector. I get so close and I don’t know why it’s not working
Ask and ye shall receive: I’ve updated the guide with some screenshots from Chrome as a visual reference. If you still run into trouble, some of the required post fields, as covered in the original version of the tutorial, may be empty. Try rearranging the JSON fields if necessary, and when all else fails, look at the contents of the AJAX response object for error messages.
