Do we have the right to return if there is a version mismatch when I buy it?, and I'm using the cloud version, I don't have a licence, can I install it, do you support me?
The themes which are listed on the website are available for Xenforo 2.2 and 2.3. If you need to know any more information about a theme before purchasing, feel free to ask here and I’ll be happy to help since refunds aren’t available for a version mismatch.
Yes, themes can be installed on the cloud version.
