Is it subdomain urls supported

Hello
Yes the plugin works for domains, subdomains and folders in multisite mode.

It will work on Gtranslate created subdomain as well?

Hello,

I have not tested the integration with the Gtranslate plugin. Try it, it should work!

I am having this login issue again and again while I configured Google api and search console as you guide. Can you help? Pls check image for detail.
