We have successfully been using domain mapping for the past 18 months.
We have just updated Plesk to 11.5.3 and wordpress is now 3.9.1
Our most recent site simply won't redirect correctly.
Top level domain - OK
New Subdomain website - Will only redirect to the Top level domain
This is the case whether the mapping is set to Primary or not.
Subdomain is set up on plesk as an alias of the top level domain, as we have always done.
Is it a plesk issue - All the previous domains map correctly.
Is it a wordpress or plugin issue?
Does sunrise.php need editing?
Does Apache need restarting?
