Moving site to subdomain I am moving our current site to a subdomain and get this: "Craft CMS requires the PHP multibyte string extension in order to run."

I have updated the $craftPath variable and System-&gt;General-&gt;SiteUrl CP setting to the updated URL.

Am I missing something?
I'm guessing the site you're setting up on the subdomain is on a new server?


  Craft CMS requires the PHP multibyte string extension in order to run.


That error means that the PHP multibyte extension isn't installed or enabled on your server and both Craft 2 and Craft 3 require it.
