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
Short answer – Nope. Any page request initializes the scheduled queue. It’s just an initialize request. Wp-cron request is a standalone request. so requesting URL /somepage you just initialize request to /wp-cron.php However – If cron event doesn’t work really well (it’s has 1000 db queries e.g. or its requesting a some really long-to-respond resource), … Read more
There is no downside for running WP CRON using the server’s cron jobs. In fact this is the recommended practice. According to Official WordPress Plugin Development Document: WP-Cron does not run continuously, which can be an issue if there are critical tasks that must run on time. There is an easy solution for this. Simply … Read more
It’s a sign that you have ALTERNATE_WP_CRON defined in your wp-config.php In order to do some background processing (like publishing scheduled posts), WordPress redirects you to the URL with ?doing_wp_cron appended.
I know I’m three months late, but the function you want here is WordPress’ get_date_from_gmt(). 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? Caching plugins can interfere with cron jobs because your visitors are not served a live page but a cached version of your page. 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
My favorite plugin for that is Core Control which has very nice module for display of what is going in the cron – which events are set up, when are they next firing, etc. On getting your hands dirty level see _get_cron_array(), which returns internal stored data for cron events (top level of keys are … Read more
Why don’t you just create a cron job, make a database dump and look where the info about the cron job is kept? That’s what I did. As suspected, WordPress 3.5.1 keeps its cron jobs in the {wp}_options table under the name ‘cron’. SELECT * FROM `wp_options` WHERE `option_name` LIKE ‘%cron%’ Or through functions.php: $cron_jobs … Read more
