I currently have a school website using the Xtheme.
i would like to be able to use the xtheme with my current domain in a spanish version of the website.
Would i have to pay for two licences on the same domain.
Or would i be better off going with a multi site or plugin translator ?
Licenses work on multi-sites or even multiple installs as long as they are on the same domain. For example http://www.example.com/english to http://www.example.com/spanish will work, however each site installed on a sub-domain should be validated separately with additional licenses for example english.example.com and spanish.example.com.
