"Attention: WordPress cron jobs seem to be broken on your site!
There are active background jobs which were scheduled to run 1 day ago, but never have been executed.
You should contact your hoster or site administrator to get this fixed as soon as possible. Until then, WP-Lister will not be able to sync the inventory correctly nor process new orders from eBay.
The quickest way to make sure this will not happen again is using an external cron job to trigger the background tasks every 5 minutes. To do so, change the "update interval" setting option to "use external cron job" and follow the instructions. This is strongly recommended if you are using WP-Lister for Amazon as well.
Keep in mind that this issue is not related to WP-Lister but to WordPress itself. All plugins and features which rely on scheduled tasks are affected by this issue - which includes scheduled posts, internal cleanup routines in WooCommerce and more.
To see all your scheduled tasks and when they were last executed, we recommend installing Debug Bar and the Debug Bar Cron extension. A possible workaround for sites with broken WP-Cron is the WP Cron Control plugin, but we recommend to find out what is causing this and fixing it instead. "
