Hello,
I have moved my wordpress to new source like https://example.co
I have not created subdmomain in control panel.
I have added DNS record as previous *.example.co and ip address.
I have tried to add server alias from my control panel with *.example.com but it showing error that invalid ,Domain names can comprise letters, digits and hyphens.
then I have added server alias for plesk like this ServerAlias “*.example.com” in conf/vhost.conf file in root
and Updated permalinks
But now it showing default server page so what process I need to do next.
