2 warnings in wp-admin/tools.php?page=permalink-manager.php

Hi,

I get the 2 php warnings below when enabling the plugin, and there are “No items found.” in the listing. The errors disappear and listing appear if I change which Post Types are listed in “Screen Options”. Changing back to the default posts/pages does not cause the warnings to reappear.

The plugin seems to behave flawlessly, otherwise. The experimental base editor works well.

Here are the warnings that initially appeared:

Warning: implode() [function.implode]: Invalid arguments passed in /var/www/vhosts/healthskills.co.uk/new.healthskills.co.uk/wp-content/plugins/permalink-manager/inc/permalink-manager-editor.php on line 137
