Thanks for your reply Prophecy. I have narrowed it down to the following code in page_post_redirect_plugin.php. Line 443. It is also referenced in lines 608 and 825.
When I remove the https://www.example.com, the drop down menu link does not work as it is pointing to a null value.
if(!isset($theArray[$key->post_id][‘_pprredirect_rewritelink’])){$theArray[$key->post_id][‘_pprredirect_rewritelink’] = 0;}
if(!isset($theArray[$key->post_id][‘_pprredirect_url’])){$theArray[$key->post_id][‘_pprredirect_url’] = ‘https://www.example.com‘;}
if(!isset($theArray[$key->post_id][‘_pprredirect_type’] )){$theArray[$key->post_id][‘_pprredirect_type’] = 302;}
if(!isset($theArray[$key->post_id][‘_pprredirect_relnofollow’])){$theArray[$key->post_id][‘_pprredirect_relnofollow’] = 0;}
if(!isset($theArray[$key->post_id][‘_pprredirect_newwindow’] )) {$theArray[$key->post_id][‘_pprredirect_newwindow’] = 0;}
if(!isset($theArray[$key->post_id][‘_pprredirect_active’] )){$theArray[$key->post_id][‘_pprredirect_active’] = 0;}
