Some of what is usually admin side functionality is not included as part of the “main” wordpress bootstrap, files containing uploaded file manipulation functions are one of them and you need to explicitly include them by adding include_once( ABSPATH . ‘wp-admin/includes/image.php’ ); into your call_import function.
In wp-includes/default-filters.php we can find a callback registration: // WP Cron if ( !defined( ‘DOING_CRON’ ) ) add_action( ‘init’, ‘wp_cron’ ); If we go the function wp_cron() now, we see this: $schedules = wp_get_schedules(); foreach ( $crons as $timestamp => $cronhooks ) { if ( $timestamp > $gmt_time ) break; foreach ( (array) $cronhooks as … Read more
The answer is apparently YES, I should worry. After some research, I’ve found that the warning seems to be related to misconfigurations on the server that WordPress is hosted on (ie. a problem with my server, not WordPress). Common misconfigurations: Server doesn’t have DNS, and so it can’t figure out who “example.com” is, even though … Read more

The function accepts a GMT/UTC date in Y-m-d H:i:s format as the first parameter, and your desired date format as the second parameter. It’ll convert your date to the local timezone as set on the Settings screen. Example usage: echo … Read more
First can you please confirm that you don’t have any caching plugins enabled?

If you have a caching plugin enabled, you can choose one of your pages, add an exclussion to your … Read more
You can create new schedule times via cron_schedules: function my_cron_schedules($schedules){ if(!isset($schedules[“5min”])){ $schedules[“5min”] = array( ‘interval’ => 5*60, ‘display’ => __(‘Once every 5 minutes’)); } if(!isset($schedules[“30min”])){ $schedules[“30min”] = array( ‘interval’ => 30*60, ‘display’ => __(‘Once every 30 minutes’)); } return $schedules; } add_filter(‘cron_schedules’,’my_cron_schedules’); Now you can schedule your function: wp_schedule_event(time(), ‘5min’, ‘my_schedule_hook’, $args); To only schedule … Read more
I think the best way is to use WP-CLI but you’d need to write a bash script to do this. Here is one that should do it for you: WP_PATH=”/path/to/wp” for SITE_URL in = $(wp site list –fields=domain,path,archived,deleted –format=csv –path=”$WP_PATH” | grep “,0,0$” | awk -F ‘,’ ‘{print $1 $2}’) do for EVENT_HOOK in $(wp … Read more
