I know this 'unable to do future ping' issue is being covered extensively, but I still could not find a solution to my special error..
I am using the http://www.skippy.net/blog/category/wordpress/plugins/wp-cron/ plugin, but at the bottom of my blog, I see the following error:
Warning: Invalid argument supplied for foreach() in /home/public_html/domain/wp-content/plugins/wp-cron-future-pings.php on line 107
Would apperciate if someone could shed some light on this. Let me know if you need more info.
Running WordPress 2.0.3 and wp-cron 1.4
