Thank you all for the reports. We’ve very sorry for the trouble, and the delay in replying on this thread.
Starting in Jetpack 4.2, we’ve made numerous changes to improve Jetpack’s performance as well as the reliability of the data used in publications managed on WordPress.com (Related Posts, Publicize, Subscriptions all rely on data synchronized from your site to WordPress.com). To improve things, we’ve made a lot of changes to the way posts are synchronized between Jetpack sites and WordPress.com.
While this has improved things for many sites, it has created issues on some sites. Here are a few of the edge cases we’ve discovered:
- Sites using a custom implementation of WordPress’ scheduling system, WP-Cron. Depending on how the core scheduling system is short-circuited, it may cause synchronization issues.
- Sites using plugins to trigger imports, or to trigger multiple scheduled actions, may in some cases block other scheduled actions like Jetpack’s Synchronization system.
- Sites with no visits, and no scheduled visits from a bot like Jetpack’s Monitoring agent, do not trigger any synchronization.
- Sites where Cron is just disabled or broken.
We’re already working on work-arounds for some of those issues, and the next version of Jetpack will address some of these edge cases. For others, that will require an intervention from your hosting provider, or a review of the plugins you’re using.
We can help you figure out how to fix things on your sites, but we’ll need details about your site setup to do so. Could you all use Jetpack’s Debugger module to send us some more information about your sites?
- Go to the Jetpack page in your dashboard.
- Click on the Debug link appearing at the bottom of the page.
- Click the link that says “click here to contact Jetpack support.”
- Fill in the description box and your name and email address. Feel free to add as many details as possible about your site in that box: your hosting provider, whether you’ve made any changes to the default WordPress scheduling system, whether your site’s
wp-config.php
file includes a mention of cron
, the plugins you use to manage your posts, …
- Click the “Contact Support” button.
- We’ll then get back to you via email.
I’d recommend against posting the debug results here, as they contain private information that shouldn’t be made public.
Thank you all, and sorry again for all the trouble.
