Disabling default cron and using wget to trigger cron

[BrettParticipant]

Hi

If i disable built in cron with define(‘DISABLE_WP_CRON’, true); in wp-config.php and call “https://mysite?wp_doing_cron” as is widely recommended, updraft plus wont trigger in a cron. This was reported already in February 10, 2020 at 7:41 pm in post #511129 “https://updraftplus.com/forums/search/cron/”

I had this happen before, so i just stopped using system crontab (as per the recommended practice). It is not a new bug, it has existed for at least a year.

As you can see below, there is a symbol error in /home/customer/www/wootest.spacenow.net/public_html/wp-content/plugins/updraftplus/class-updraftplus.php:2809

I read as part of doumentation that ?doing_wp_dron loads classes differently, you may not have all the PHP symbols you expect (it is cut down).

If updraftplus is being called as part of ?doing_wp_cron, you may have to define your own symbols or act differently if the expected ones or full wp environment are not available.

Updraft plus does complain that events are not being run by cron, this is false, it is being run, just that the run fails within updraft classes with a stacktrace

Hi Brett,

Please could I confirm, are you calling https://example.com/wp-cron.php?doing_wp_cron (note the /wp-cron.php)?
How often is the cron job scheduled for?

Best Wishes,
Dee
