  • [Tue Oct 29 22:11:46 2013] [error] [client xxx.xxx.xxx.xxx] PHP Fatal error: Call to undefined function get_core_checksums() in xxx/wp-admin/includes/class-wp-upgrader.php on line 1526, referer: https://xxx.com

    Have tried from multiple management sites and still getting same error.

    It does not appear to be allowing upgrading of WordPress. Although if you go directly into the backend of a site the update button does work.

    get_core_checksums() was added in 3.7. So was the code that calls get_core_checksums().

    wp-admin/includes/update.php must not have been updated when you updated to 3.7.

    The good thing is, this checksums code is actually used to help verify that files *did* copy. So you should have less trouble with sneaky problems like these in the future.

    I manage ~50 sites using a central management tool and EVERY site is now giving this error, with the 3.7.1 update. I think there is something larger going on.

    I should clarify, I’m using InfiniteWP (a different tool), but the exact same error… so it’s not just WP Management Sites that’s having this issue.

    I had the same problem updating the websites I manage with InfiniteWP too. Updating the ‘InfiniteWP – Client’ plugin to the latest version (v1.2.5) fixed the problem for me.
