I have tried that, but it still was happening.

I believe my issue is the same as this one reported on Github; https://github.com/Automattic/wp-super-cache/issues/84

As someone suggested I tried setting up direct cache on the homepage and blog page. This seems to have fixed the issue of other pages/posts disappearing too frequently, however as the same person also mentions this causes another bug; https://github.com/Automattic/wp-super-cache/issues/149

It is surprising that such old bugs(almost 2 years) are still existing.

Yes, this is what I was referring to in the first post.

Here are the settings;

On this site I have “define(‘DISABLE_WP_CRON’, true);” set so I run it manually with a cron job every 15 minutes.

I thought that may have been when the cached files were getting removed, but I temporarily disabled the cron for testing and it still happened.
