I just encountered this very same problem. I was trying to do wp_insert_post() from within a cron action, and the script would apparently just die during some save_post action handler. I tracked down my problem, which turned out to be a save_post handler which is used to save the POST data from a custom metabox. … Read more
Plugins such as WP Super Cache have a setting for that. It’s called “pre-load”, it allows you to pre-load pages and you can set an specific interval to regenerate cache. If you publish at least 3 or 4 times a week a good configuration could be every 4000 minutes.
You should be including this file: include( “/some/path/wordpress/wp-config.php” ); That’ll get you to where you can use the wp_insert_post() function. If this is a multi-site blog, make sure to use the switch_to_blog() function first.

You could run your wp-cron job every day and check the date, similar to this but with a simple callback like: cron_callback_wpse_113675() { $date = date(‘d’); if (’01’ == $date || ’15’ == … Read more
“Error establishing database connection” when trying to run script through crontab
After some testing I figured out that yes, it will use the new schedule, updated using the ‘cron_schedules’ filter.
You’re getting Undefined index errors because you’re loading the files directly and not rendered through the server. The server typically populates those values and it’s actually more secure to run with less elevated privileges (through an HTTP request). Throw your manual cron to a curl or wget — whichever you have installed on your server. … Read more
