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

    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.
