Jetpack 4.8 was released yesterday with PHP code that caused fatal errors on sites running PHP versions lower than 5.4. While we do our best to test things prior to release, sometimes things fall through the cracks. We’re sorry for any inconvenience for the errors this code may have caused.
This release fixes that issue, as well as a few other bugs.
PHP Version Incompatibility
The updates to Sitemaps in 4.8 included PHP syntax that is only valid in versions 5.4 and higher. This has been updated to support down to PHP 5.2 and we’ve tightened our automated testing to better help prevent this in the future.
There was an incompatibility with WP Rocket and our Sitemaps after we updated the feature in 4.8. We worked closely with the WP Rocket team to get this fixed as soon as possible and the fix is in both this Jetpack release and in the latest version of WP Rocket.
User Interface Fixes
The new Settings interface had a couple of minor bugs that were squashed. Clicking the info icon will no longer jump to the top of the page, and the anti-spam card on the dashboard will no longer display the wrong status.
Note about failed updates
In Jetpack 4.8, we had added a lot of new files, most of which are new translation files for languages that have a considerable percentage of translations completed by our community members. Unfortunately, the extra language files caused updates to not complete properly on sites with limited resources that can’t fully process large zip files or copying lots of files when updating a plugin.
If you’re experiencing errors after updating to Jetpack 4.8 due to an incomplete upload or update:
- Using FTP, log into your site and navigate to and delete the
- Download the most recent version of the Jetpack plugin here.
- Then, manually install the plugin via FTP/SFTP.
This process will most likely fix this problem for you. If you still have trouble after manually updating over FTP/SFTP, get in touch with Jetpack Support.
