For WP Super Cache, it’s not well documented, but there appear to be two ways to accomplish this. Ignore ALL $_GET parameters: Under Wp Super Cache Settings > Advanced, there is a checkbox labeled “Don’t cache pages with GET parameters. (?x=y at the end of a url)”. This would mean that any URL would be … Read more
You must be doing something really wrong and no caching solution is going to solve it. Disable plug-ins on WordPress that you don’t really need. If you use it once a month, you can enable it, use it, then disable it again. For example, I had bbPress installed but wasn’t really using it and it … Read more

I found where the problem was. Everything was working correctly, but I was uploading the wrong version of the php file in question. User error, indeed, but in the process I learned a lot about the WP cache.
Get post id of permalink for a specific custom post type?
Using the Network tool in the Inspector I found out that there was a third party caching service in action. “Cloudflare” via Bluehost.
Last time I used this plugin, you had to flush the entire cache to do this: add_action(‘save_post’,’custom_clear_wp_super_cache’); function custom_clear_wp_super_cache($post_id) { if (function_exists(‘wp_cache_clear_cache’)) {wp_cache_clear_cache();} } There may (or may not) be a method of flushing the cache for a particular post now.
As the caching usually doesn’t work on parts of the page, but on the whole page, you can’t have it just not cache that specific part (well, you could use ESI/Edge Side Includes, but that’s not an option for all implementations).
