Hi,
Thanks for the screenshot.
The July backup is the last completed backup run. That will only be replaced if a new successful backup is completed.
“Warning: WordPress has a number (17) of scheduled tasks which are overdue. Unless this is a development site, this probably means that the scheduler in your WordPress install is not working”.
It appears that there is an issue with the WordPress scheduler. WordPress is not able to call the WP-Cron system to process the scheduled tasks.
Could you try adding the following line of code to your wp-config.php file (above the ‘stop editing’ line):
define( ‘ALTERNATE_WP_CRON’, true );
This will enable the alternative WordPress Cron system. This is designed to allow scheduled tasks to be processed when the main WP Cron is not able to run.
Could you then attempt a new backup?
Regards,
Bryle
