Hi Lopo,
It happens on custom posts and standard pages. Standard Posts seem to work okay
For Standard Posts – cloned post appears after clicking ‘Clone’
For Standard Pages – page does not appear after clicking ‘Clone’, need to refresh the page for it to appear
For Custom Posts – post does not appear after clicking ‘Clone’, need to refresh the page for it to appear
The custom posts are part of the theme and are defined in functions.php
Let me know if you need more details.
Thanks,
Mark
