I am pleased you are offering a good service here, and hope you the best with it.
As for the duplicate post plugin issue with WP Robot, it is very easy to fix. All you do is this:
In wp-content/plugins/delete-duplicate-posts.php, you
find and delete the filter_cron_schedules function.
Then add this code to replace it:
Code:
function filter_cron_schedules( $param ) {
/* fixed by KenBlack */
return array_merge(array( '30min' => array(
'interval' => 1800,
'display' => __( 'Every 30 minutes'
))), $param);
}
After this, WP-Robot will now work, as will the duplicate post plugin. If your keywords remain at 1970, simply delete, then add them again. This can happen if you enabled WP-Robot after enabling the duplicate post plugin.
Thanks again.
