“Specific Posts” not loading, and a workaround

I’ve been having the issue of the “Specific Posts” option not loading posts, instead just the three dots (…). I’m not able to use the shortcode method instead, because I need the snippet to appear in the header. I have a CDN and caching enabled on my site. I’m not sure if server performance or theme/plugin conflict is the problem. I will add that posts WERE loaded ONE TIME, from which I was able to choose two, but I haven’t been able to get them to load again since then. I can’t even see which posts were chosen for that snippet, although I see it’s working properly for those two alone.

I noticed this has been an ongoing issue for others as well:

• https://wordpress.org/support/topic/post-list-shows-when-selecting-specific-posts-in-site-display/
• https://wordpress.org/support/topic/post-list-loading/
• https://wordpress.org/support/topic/not-finding-posts-2/
• https://wordpress.org/support/topic/plugin-does-not-work-for-specific-posts/

I also see that even the current method of choosing specific posts does not work for some people, because the method of selection involves using page titles, not post IDs:

• https://wordpress.org/support/topic/add-header-footer-to-specific-post-based-on-post-id/
• https://wordpress.org/support/topic/selecting-solely-by-page-title-is-insufficient/

This is a great plugin, and this stands out to me as the only major limitation to plug-and-play functionality. Pages, categories, post types, and tags lists load fine every time.

My suggestion for 99 Robots, to solve both problems, is to allow users to specify something like a comma-separated list of specific post IDs in a text field, instead of loading ALL posts and using their titles, since that can be both cumbersome and/or confusing.

For plugin users struggling with this issue, my workaround has been to add a common tag to all posts I want to include a certain snippet, and then use “Specific Tags” for site display, specifying that common tag.
