I have a multi-site or multi-lingual site, do I need a multi-site license?
Note: this information goes for both multi-site and multilingual site installs.
That all depends on how many WordPress installs you have.
Do you have 1 domain name and 1 WordPress install? You just need a single license, no matter how many sites or languages you have!
If you have more than one domain name or multiple WordPress installs, you’ll need a license that allows for the number of installs you have.
