Properties are mysteriously disappearing
This is almost always because you have the real-time feed running on two sites. Please ensure it's not running on an old development site or similar.
If you have a staging and live site that are kept in sync automatically, and it's hard to always ensure it's turned off on the staging site, you can ensure requests are only sent from one place using something like so:
add_filter( 'ph_zoopla_rtdf_perform_request', 'disable_zoopla_rtdf_requests' );
function disable_zoopla_rtdf_requests($perform)
{
if ( $_SERVER['SERVER_ADDR'] != '111.111.111.111' ) // Should contain the IP of the live server
{
return false;
}
return $perform;
}
