I have a multisite subdomain network. I'm trying to create a subsite with subdomains in Thai language.
In wp-admin/network/site-new.php Add New Site is not recognizing the Thai for the subdomain name - showing error "Missing or invalid site address." (an internationalized Thai domain name is working, just subdomain site address is not)
I tried using the Internationalize WordPress (IntlWP) activated/enabled it but still getting site address error
Any ideas? seems like there should be more than one plugin or approach to using Asian languages as subdomain. Thanks
