Sorry about that! We’ve made some changes to the Sitemaps feature in Jetpack 4.8, and inadvertently used code that isn’t compatible with old versions of PHP (PHP 5.3 or less). That’s most likely what’s causing the issue on your sites.
We’ll release a new update to solve that problem, but until then I’m afraid I can only recommend the following:
- Contact your hosting provider and ask them if it is possible for you to use a more recent version of PHP. PHP 7 is the recommended version of PHP for WordPress, so if they can update you to PHP 7 that would be great.
- Remove the Jetpack plugin from your site until we release an update.
- Force Deactivate the Sitemaps module by installing this must-use plugin on your site. You can do so by following the instructions in the file.
Really sorry for all the trouble!
I’ll post again here once I have some news.
Sorry everyone for all the trouble! We’ve just released 4.8.1 to solve the issue mentioned in this thread.
You can read more about this release here:

Please update to 4.8.1 as soon as possible to see if that fixes that issue for you. Also, if you’re using WP Rocket, please update that to the latest version as well.
If you continue to experience issues, could you please try to delete the Jetpack plugin, and reinstall it from scratch? If that doesn’t help either, you can start a new thread here with as much information as possible about the errors you see on your site:

Thank you, and again, sorry for the trouble! While we do our best to test things prior to release, sometimes things fall through the cracks. We’ve added additional measures to make sure this type of error doesn’t happen again.
