Ticket #61489 – Description
initial v1 1 1 Today we had around 20+ sites go down sporadically across multiple servers and hosting providers. All of the sites were on 6.1.7 or 6.2.6 and had the same errors: 2 PHP Fatal error: Uncaught TypeError: call_user_func_array(): Argument #1 ($callback) must be a valid callback, function “_wp_footnotes_kses_init” not found or invalid function name in /wp-includes/class-wp-hook.php:308 2 `PHP Fatal error: Uncaught TypeError: call_user_func_array(): Argument #1 ($callback) must be a valid callback, function “_wp_footnotes_kses_init” not found or invalid function name in /wp-includes/class-wp-hook.php:308` 3 3 4 After verifying checksums on core we found that the wp-includes/default-filters.phpfile did not match and we had to re-download core on all the sites to get rid of the critical error. I imagine this will be happening for us most of the day. We checked server and security logs and didn’t find anything correlated to the issue and believe it may be something to do with the update methods. Not sure but some insight here would be helpful.4 After verifying checksums on core we found that the `wp-includes/default-filters.php` file did not match and we had to re-download core on all the sites to get rid of the critical error.
