So no MDP active/visible – After ‘Network deactivate’ and activate again, the error disappears – When opening a page again the MDP is still active/ visible * After a while testing I found this to resolve the problem: * (Deactivating/activating the MDP plugins can first solve the error issue, but the following two steps solves the problem directly) – On the primary site I set the MPD restriction to ‘No Restriction’ and saved it – On the primary site I set the MPD restriction back to ‘Templates’ and saved it – Every thing look fine again * Hope this info is helpful to solve the issue. * Regards, * Walter Kamer * [https://wordpress.org/plugins/multisite-post-duplicator/](https://wordpress.org/plugins/multisite-post-duplicator/) Viewing 10 replies - 1 through 10 (of 10 total) * Plugin Author [MagicStick](https://wordpress.org/support/users/magicstick/) * (@magicstick) * [9 years, 11 months ago](https://wordpress.org/support/topic/mpd-not-working-properlyerror/#post-7535589) * Thank you very much for the info Walter. These are actually only Warning messages because you have ‘debug mode’ on. MDP should still function as expected. I will add a fix to ensure the warning messages don’t appear in debug mode in a future release! * Thanks again! * Thread Starter [Walter Kamer](https://wordpress.org/support/users/broadloommedia/) * (@broadloommedia) * [9 years, 11 months ago](https://wordpress.org/support/topic/mpd-not-working-properlyerror/#post-7535602) * I’m not aware of having ‘debug mode’ on. This is really an error, because the MPD will be visible on new sites added (with this warning/error message), while this should not because I selected only one master. And while the MPD is visible on the new sites you can copy pages to other sites! So really this is not only a warning message. * Plugin Author [MagicStick](https://wordpress.org/support/users/magicstick/) * (@magicstick) * [9 years, 11 months ago](https://wordpress.org/support/topic/mpd-not-working-properlyerror/#post-7535608) * Hi Walter. Thanks for the follow up. Can you turn off debug mode and and report back if there are still problems? * Go into your wp-config.php file on your site root directory and change line: * `define( 'WP_DEBUG', true );` * to * `define( 'WP_DEBUG', false );` * [https://codex.wordpress.org/Editing_wp-config.php#Debug](https://codex.wordpress.org/Editing_wp-config.php#Debug) * Thread Starter [Walter Kamer](https://wordpress.org/support/users/broadloommedia/) * (@broadloommedia) * [9 years, 11 months ago](https://wordpress.org/support/topic/mpd-not-working-properlyerror/#post-7535610) * Hey MagicStick, * define(‘WP_DEBUG’, false); is already in de wp-config.php * Plugin Author [MagicStick](https://wordpress.org/support/users/magicstick/) * (@magicstick) * [9 years, 11 months ago](https://wordpress.org/support/topic/mpd-not-working-properlyerror/#post-7535612) * Thanks walter.
