hello everyone!

so, i have a doubt about this theme and some plugins: why I can only use 1 theme/plugin that asks for licence in just one single website?

I have 2 oxwall websites, but if I put a licence key in one, the other will alert me to put the key for some reason...

The question is: is possible to use one licenced theme or plugin in 2 or more oxwall websites? if yes, how do i do it? thanks!
