[Plugin: WP Super Cache] Issue with Scheduled Posts Not Showing Up

Or email me at donncha @ ocaoimh.ie giving me a login/password to your site (ftp and WordPress) so I can debug it myself. Could be another plugin that’s causing the status to be draft.

Have you tried the development version? https://downloads.www.ads-software.com/plugin/wp-super-cache.zip

I’d be very interested in seeing if the Dev version helps correct this, so anyone trying it please post!

@cldswm – If reverting to 1.0 (I did the same), I’d make sure that you also replace the .htaccess rewrite rules (if using the advanced caching mode) just in case.

I suspect this might be related to the introduction of a new filter I used to clear the cache and the function that does the clearing checked if it had been called twice.

I have made a change to the plugin. You can either:
1. Edit wp-content/plugins/wp-super-cache/wp-cache-phase2.php in your favourite text editor and remove the line that mentions “clean_post_cache”
add_action( 'clean_post_cache', 'wp_cache_post_edit' );
2. Download the development version and overwrite all the files in wp-content/plugins/wp-super-cache/ with those files.

If you update to the dev version that filter is still there because it’s a regular part of WordPress, but I moved the “check if it runs twice” bit of code around so it only checks after a post is published. If it’s a draft post then it doesn’t remember that run. Confused? Just try it and tell me if it helps please.

Donncha,
Thanks for tracking this down. The fix works. On the same test installation where I experienced the problem with 1.1, I removed 1.1 and installed the dev version. Now, when a scheduled post is published via wp-cron, the cache is cleared as expected. Here’s a log excerpt:

Thank you.

It’s really weird. The clearing functions see a draft post but the second time they run they see a published post. Really odd but glad this fixes it. Expect a new release soon!

Donncha,
Bonus points to you, as this fix appears to resolve the other issue I experienced with 1.1, where requests not desiring compression would nevertheless get gzipped responses (request headers lacking an accept-encoding:gzip header would still get gzipped output–see href=”https://www.ads-software.com/support/topic/plugin-wp-super-cache-gzip-bug).

Now compressed content is returned only if a client says it’s OK to:

Very happy about this! Thanks!

Have had the same issue reported to me from readers, the site auto tweets new posts, yet people visiting the home page couldn’t find them.
Turned on debugging on a post I just scheduled and got the same issue with post is draft do nothing.
About to install the dev version.

Hi, just to say that I’m having the same issue on both my blogs where I use WP Super Cache.
I’ve just edited the wp-cache-phase2 file, I hope this should solve the problem.

Thanks!

Doc75 – or try the development version, that should fix it and I’d love to get some feedback, artesea – did it help?

https://ocaoimh.ie/the-development-version-of-wp-super-cache/

I’m having this same problem on a blog that receives a lot of views. Is there somewhere that I can download v.1.0 to revert to?

Not comfortable using the aforementioned hack or a dev version–need stability.

Thanks!

tbadorrek – the dev version will be the stable version in a day or two, it is very stable.

Hi, editing the file did not solve the problem. I’m now installing the development version.
I’ll let you know.

Thanks.

Editing the file did not work for me either.

tbadorrek – so try the dev version. That will fix it.
