Folding Category List (FoCaL)
PHP error on every page load with FoCal (1 post)

    My php-fpm error log is filling up with these:

    PHP Warning: call_user_func_array() expects parameter 1 to be a valid callback, second array member is not a valid method in /etc/httpd/htdocs/test.wtb.com/wp-includes/plugin.php on line 406

    I confirmed that they are coming from FoCal by turning off plugins 1 by 1 until the error messages stopped. But I haven't been able to find the problem.
