wp_insert_post() return value says:
(int|WP_Error) The post ID on success. The value 0 or WP_Error on
failure.
Okay, I’ have an import routine running and all but a few (about 20) of them import correctly. The ones that fail have a return value of 0 but is_wp_error() is NOT true. How do I find out what happened and why these certain articles won’t import properly? At least if is_wp_error() was returned you could print out the message.
Thanks.
P.S. Here is the code that adds the article. Note: I’m also not sure why AdminNotice::displayError doesn’t do anything (that’s why I added log output). Am I supposed to put some type of tag on the page (it’s my first ever plugin for a single task)? I got that bit of code from How to add an admin notice upon post save/update
/**

* @param $title The title of the article
