 * Sorry for not answering when the issue was resolved.
 * It was indeed a bug in the plugin Real Cookie Banner throwing a PHP fatal error
   and therefore breaking cache preload.

 * [@kingofrocknroll](https://wordpress.org/support/users/kingofrocknroll/) as you
   probably saw, I’m having the same problem and also noticed the PHP error caused
   by Real Cookie Banner in the log file: [Cache preloading doesn’t work anymore | WordPress.org](https://wordpress.org/support/topic/cache-preloading-doesnt-work-anymore/)
 * I just don’t have enough knowledge to know whether the two things are related.
   Did you already contact the support of Real Cookie Banner about the PHP error?

 * The Issue is has been resolved. The problem seemed to be on the side of WP Optimize
   since users in their support forum also mentioned similar conflicts with other
   plugins. WP Optimize released an update, the release note saying “FIX: Cache –
   Compatibility issue with other plugins due to late start of output buffering”
 * Now everything works fine again.

 * Thanks for the quick reply. Do you have any suggestion for a caching plugin offering
   preloading where this problem doesn’t occur or are you afraid that this is more
   like a fundamental problem “WP External Links vs. preloading”?
